Abstract:
AIM: To determine whether the different diameters of a specific intraocular lens (IOL) have significantly different optimized SRK/T A constants and whether these new A constants can improve refractive outcomes. METHODS: Data were collected prospectively from Jan. 2011 to Dec. 2012 on all patients undergoing routine cataract surgery at a district general hospital in the UK. Patients were divided into three groups according to the size of the Akreos AO MI60 IOL used. A constants for the SRK/T formula were optimized according to the size of the IOL. These optimized A constants were then used to select future refractive outcomes. RESULTS: A total of 2398 cataract operations were performed during the study period of which 1131 met the inclusion criteria. The three optimized A constants for the different sized IOLs were 118.98, 119.13, 119.32. The difference between them was highly significant (P≤0.0001). Two optimized A constants for three sizes of IOL led to an improvement in refractive outcomes (from 93.4% to 94.6% of refractive outcomes within 1.00 D of predicted spherical equivalent). The optimized A constant for the largest IOL was based on a small number of cases and was not used. CONCLUSION: Optimizing the A constant for the three distinct sizes of the Bausch & Lomb Akreos MI60 lens lead to three significantly different A constants. In our practice, using two different optimized A constants for three different sized IOLs give the least refractive error, however, using three optimized A constants may give better results with a larger dataset.

Abstract:
Introduction: Cataract surgery with insufficient capsular support has become an intense challenge to surgeons in intraocular lens (IOL) selection. Anterior chamber IOL (ACIOL), iris-claw (Artisan) IOL, and scleral-fixated IOL (SFIOL) are the three common types of IOL used. However, each type of IOL has its own characteristics and different clinical requirements. IOL selection is important in ensuring good visual outcome. Purpose: The purpose is to compare the duration or surgery, visual outcomes, and complications among ACIOL, Artisan IOL, and SFIOL. Study design: Retrospective comparative analysis. Material and methods: This is a four-year retrospective analysis of patients who underwent either ACIOL, Artisan IOL, or SFIOL implantation between January 2014 and January 2018. Patients were divided into ACIOL, Artisan, and SFIOL groups. Demographic data, duration of surgery, preoperative and postoperative visual acuity, and postoperative complications were identified and compared among the different groups. Results: Sixty-four eyes from 58 patients were analysed: twenty (31.3%) eyes with ACIOL, 28 (43.8%) eyes with Artisan, and 16 (25%) eyes with SFIOL. Mean surgery times for ACIOL, Artisan, and SFIOL were: 61 ± 27.8, 64 ± 26.9, and 104.1 ± 46.8, respectively. SFIOL showed significantly longer surgery time than the ACIOL and Artisan groups (p < 0.05). There was no significant difference in surgery time between the ACIOL and Artisan groups (p > 0.05). The Artisan group showed significantly better visual recovery at postoperative 1 week than both the ACIOL and SFIOL groups (Artisan vs ACIOL: 6/18 vs 6/24, p < 0.05; Artisan vs SFIOL: 6/18 vs 6/60, p < 0.05). However, final best-corrected visual acuity (BCVA) at two months was comparable among all three groups with a median BCVA of 6/9. Elevated intraocular pressure occurred in all IOL groups, retinal detachment developedin the Artisan and SFIOL groups, epiretinal membrane developed in the ACIOL and SFIOL groups, corneal decompensation developed in the ACIOL group only. Cystoid macular oedema and IOL tilt occurred in SFIOL only. Conclusions: All three groups of IOL showed comparable good visual outcomes. The decision of IOL selection should be based on patients’ clinical condition and availability of surgical skill and resources.

Abstract:
A 88-year-old female who was being treated for end-stage pseudoexfoliation syndrome was referred to our hospital for treatment of dislocated intraocular lens (IOL) and the elevated intraocular pressure (IOP) and in the right eye (RE). At the first visit to our hospital, best-corrected visual acuity (BCVA) was 0.2 in the RE and 0.02 in the left eye (LE). IOP was 47 mm Hg in the RE and 21 mm Hg in the LE. Slit-lamp examination showed no abnormalities in anterior segments and dislocated IOL in the RE. Fundus photograph showed optic disc pallor in both eyes. We performed the combined therapy of flanged intrascleral IOL fixation with the double-needle technique and trabeculectomy. Throughout the follow-up period, BCVA slightly improved from 0.2 to 0.4 in the RE. The angle of tilt of the IOL was 6.6, 7.9, and 8.7° as measured by swept-source optical coherence tomography at 1, 4, and 6 months after the surgery, respectively. The IOP remained less than 10 mm Hg without having to administer any other glaucoma medications. Furthermore, any complications associated with the surgery were not confirmed.

Abstract:
Purpose. To analyze the frequency, terms and risk factors of late IOL dislocation. Material and methods. A retrospective cohort study was conducted based on archival data of 70 787 cases of the senile cataracts phacoemulsifications performed in 2002–2019 years. Statistical processing of the results and Kaplan–Meier analysis were performed using the SPSS 11.0 program (STATA). Results. 320 patients in the study group were treated for late IOL dislocation at various postoperative periods. The average age of the patients was 76.2±12.5 years at the moment of reconstruction procedure. The periods from the moment of IOL implantation to its dislocation varied from 4 months to 17.58 years, the average term was 6.95±3.67 years. IOL reposition was performed in 272 cases (85.0%) and IOL change – in 48 cases (15.0%). The leading risk factor was pseudoexfoliation syndrome detected in 239 patients (74.7%). Among other factors there was high myopia (72 patients; 22.5%), in 78 cases there were the surgery procedures between cataract surgery and IOL dislocation: glaucoma surgeries – 27 cases (8.4%), vitreal surgeries – 9 cases (2.8%), laser discission of secondary cataract – 42 cases (13.1%). The cumulative 5-, 10-, 15-, and 18- year risk of late IOL dislocation was estimated using Kaplan–Meier analysis. Conclusion. The dynamics of the number of reconstructive operations at late IOL dislocations has a tendency to increase. The average term from the IOL implantation to its dislocation was 6,95±3,67 years. The leading risk factor was pseudoexfoliation syndrome. The cumulative 5-, 10-, 15-, and 18-year risk of late IOL dislocation was 0.2; 0.7; 1.15; and 1.4%, respectively. Key words: intraocular lens, dislocation, phacoemulcification.

Abstract:
We evaluated the rotational stability of a new toric intraocular lens (IOL), HOYA XY-1 toric IOL that is an improved version of HOYA 355 toric IOL, with longer overall length (13.0 mm vs. 12.5 mm), shortened unfolding time, and texture processing of the surface of haptics. Data from 193 eyes of 165 patients (76.4 ± 8.3 years old) with preoperative corneal astigmatism exceeding 0.75 diopters who had undergone phacoemulsification and toric IOL implantation were collected and analyzed. Corneal astigmatism, refractive astigmatism, and uncorrected (UDVA) and corrected distance visual acuity (CDVA) were evaluated before and 1 day, 1 week, and 1 month after surgery. The degree of IOL decentration, IOL tilt, and toric axis misalignment was assessed at 1 day and 1 month postoperatively. Fifty eyes received AcrySof toric IOL, 51 eyes TECNIS toric IOL, 46 eyes HOYA 355 toric IOL, and 46 eyes HOYA XY-1 toric IOL. The amount of axis misalignment from the intended axis was significantly different among IOLs (p = 0.004, one-way ANOVA), and HOYA XY-1 showed significantly less amount of axis misalignment than TECNIS (p = 0.020, Tukey’s multiple comparison) and HOYA 355 (p = 0.010). The proportion of eyes that showed axis misalignment <10° at 1 month postoperatively was significantly higher with HOYA XY-1 toric IOL than with other toric IOLs (χ2 test, p = 0.020). HOYA XY-1 toric IOL, the modified version of HOYA 355 toric IOL, showed excellent rotational stability in comparison with other models of toric IOLs.

Abstract:
Abstract Background: Opacification of ophthalmic devices has been previously reported in silicone scleral buckle, Molteno implant, and intraocular lens opacification. However, there is no report on polymethyl methacrylate (PMMA) intraocular lens (IOL) calcification. Objective: Report the clinical feature, histopathologic and spectrophotometer analysis of opacified three-piece PMMA IOL. Method: A 60-year-old diabetic patient reported decreased visual acuity in her right eye, which had undergone phacoemulsification with PMMA IOL implantation. The ophthalmic examination revealed a white homogeneous opacification of posterior surface of the IOL. The explanted IOL was analyzed using scanning electron microscopy, energy dispersive spectroscopy, and alizarin red staining. Results: The scanning electron microscope analysis showed granular deposits on posterior surface of the IOL. Using energy dispersive spectroscopy analysis, calcium and phosphate peaks were revealed, which was confirmed by positive for alizarin red staining. Conclusion: This case report provided evidence of PMMA IOL calcification caused by calcium and phosphate deposits. The possible etiologies were extrinsic and/or intrinsic factors.

Abstract:
More and more patients who have had corneo-refractive surgery present for intraocular lens (IOL) implantation. IOL calculation in these patients is still a challenge. After refractive surgery, if eyes are treated as normal eyes, high hyperopic errors can occur in previously myopic eyes and moderate myopic errors in formerly hyperopic eyes. Three main sources for these errors can be identified: the radius measurement error, the keratometer index error and the IOL formula error. The literature presents a confusing variety of procedures and formulas to cope with this situation. An analysis of the available literature reveals the different methods used to address the individual error contributions, the magnitude of which is assessed by model calculations. The most relevant formulas for clinical practice are the no-history procedures, which require no previous patient data. Using these methods to calculate IOL power after refractive surgery makes it possible to obtain clinical outcomes of a similar quality to that for normal eyes.

Abstract:
Summary:An overview on polypseudophakia (‘piggyback’ intraocular lens [IOLs]) is given. Requirements on a sulcus-supported supplementary IOL are defined. Two-year results of a new IOL (Sulcoflex®) are presented and indications for this IOL are defined.Methods:The IOL is especially designed for implantation into the ciliary sulcus in pseudophakic eyes (piggyback). It is a single-piece implant made of hydrophilic acrylic. Optic- and haptic-edges are round. The optic has a diameter of 6.5mm and a concave/convex shape for perfect fit on the anterior convex surface of the primary IOL. The haptic is angulated, and has an undulated design to preclude IOL rotation. A monofocal, a multifocal or a toric version of the sulcoflex IOL were implanted into the ciliary sulcus of pseudophakic eyes. All IOLs were implanted by injector through a 3mm clear cornea incision. After surgery near and far uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA) and eye pressure were assessed. Inflammation was measured by laser flare/cell meter. Position and rotational stability of the IOL were documented regularly at all control visits. Furthermore, Scheimpflug photography and ultrasound biomicroscopy were performed.Results:Surgery was performed without any complication in all cases. Two years after surgery there were no severe intra- or post-operative complications detected. Emmetropia was achieved in all cases (±0.25dpt) and the refraction was stable. Flare values were lower than the values measured after standard cataract procedures. Rotational stability and centration were excellent. Intraocular pressure was within the normal range at all visits. After one year of follow-up no iris-chafing was documented. In all cases, a good distance was found between iris and the Sulcoflex-IOL and primary implant and the Sulcoflex-IOL. In those cases with the multifocal IOL-version all patient achieved independency from glasses.Conclusion:Surgery with implantation of a sulcus-IOL is safe and less traumatic than IOL-exchange. The material and design of the Sulcoflex IOL ensure that the implants are well tolerated within the eye. The implant can be used at the same time with the primary implant or as secondary implant. Indications for implantation of this IOL are the correction of ‘post-surgical’ ametropia, of astigmatism (toric IOL) of higher order aberrations (aspherical IOL) and of ‘pseudophakic presbyopia’ (multifocal IOL). In the future, other potential indications will be established.

Abstract:
This series of case reports describes six eyes from five patients that underwent intraocular lens (IOL) exchange with scleral-fixated IOLs for cystoid macular oedema associated with iris-fixated IOLs between 2005 and 2015. Macular oedema was assessed using ocular coherence tomography (OCT). The six eyes in this series were treated by IOL removal and implantation of a scleral -sutured IOL with four points of fixation in the sulcus. Visual acuity improved in all six eyes. On OCT, macular oedema resolved after 3 months in all eyes. There were no surgical complications from the IOL exchange. One eye had a pupilloplasty and another had a diaphragm IOL to treat a major iris impairment from prior surgeries. The cause of cystoid macular oedema in these cases remains controversial but has been well recognized in eyes with iris-sutured IOLs. The absence of sutures with posterior fixation of an iris claw IOL prevents progressive corneal endothelial cell loss but does not prevent macular oedema, even in vitrectomized eyes. In conclusion, macular oedema resolved and visual acuity improved after implant exchange with a secondary scleral-fixated IOL in these cases. This procedure should be considered as a solution to persistent symptomatic cystoid macular oedema from an iris-fixated implant.

Abstract:
L’Opacification Capsulaire Postérieure (OCP) est la fibrose de la capsule développée sur la lentille intraoculaire implantée (LIO) suite à la dé-différenciation de cellules épithéliales cristalliniennes (LECs) subissant une transition épithélio-mésenchymateuse (EMT). La littérature a montré que l'incidence de l’OCP est multifactorielle, dont l'âge ou la maladie du patient, la technique de chirurgie, le design et le matériau de la LIO. La comparaison des LIOs en acryliques hydrophiles et hydrophobes montre que les premières ont une OCP plus sévère, médiée par la transition EMT. En outre, il est également démontré que l'adhérence des LECs est favorisée sur des matériaux hydrophobes par rapport à ceux hydrophiles. Une stratégie biomimétique destinée à promouvoir l’adhérence des LECs sans dé-différenciation en vue de réduire le risque de développement de l’OCP est proposée. Dans cette étude, les peptides RGD, ainsi que les méthodes de greffage et de quantification sur un polymère acrylique hydrophile ont été étudiés. La surface fonctionnalisée des LIOs favorisant l'adhérence des LECs via les récepteurs de type intégrine peut être utilisée pour reconstituer la structure capsule-LEC-LIO en sandwich, ce qui est considéré dans la littérature comme un moyen de limiter la formation de l‘OCP. Les résultats montrent que le biomatériau innovant améliore l'adhérence des LEC, et présente également les propriétés optiques (transmission de la lumière , banc optique) similaires et mécaniques (force haptique de compression, force d'injection de la LIO) comparables à la matière de départ. En outre, par rapport au matériau hydrophobe IOL, ce biomatériau bioactif présente des capacités similaires vis à vis de l’adhérence des LECs, le maintien de la morphologie, et l'expression de biomarqueurs de l’EMT. Les essais in vitro suggèrent que ce biomatériau a le potentiel de réduire certains facteurs de risque de développement de l’OCP
Posterior Capsular Opacification (PCO) is the capsule fibrosis developed onto the implanted IntraOcular Lens (IOL) by the de-differentiation of Lens Epithelial Cells (LEC) undergoing Epithelial-Mesenchymal Transition (EMT). Literature has shown that the incidence of PCO is multifactorial including patient’s age or disease, surgical technique, and IOL design and material. Reports comparing hydrophilic and hydrophobic acrylic IOLs show the former has more severe PCO after EMT transition. Additionally, the LEC adhesion is favored onto the hydrophobic materials compared to the hydrophilic ones. A biomimetic strategy to promote LEC adhesion without de-differentiation to reduce PCO development risk is proposed. RGD peptides, as well as their grafting and quantification methods on a hydrophilic acrylic polymer were investigated. The surface functionalized IOL promoting LEC adhesion via integrin receptors can be used to reconstitute the capsule-LEC-IOL sandwich structure, which is considered to prevent PCO formation in literature. The results show the innovative biomaterial improves LEC adhesion, and also exhibits similar optical (light transmittance, optical bench) and mechanical (haptic compression force, IOL injection force) properties comparing to the starting material. In addition, comparing to the hydrophobic IOL material, this bioactive biomaterial exhibits similar abilities in LEC adhesion, morphology maintenance, and EMT biomarker expression. The in vitro assays suggest this biomaterial has the potential to reduce some risk factors of PCO development

Abstract:
The primary function of the lens of the eye, termed accommodation, is to precisely focus light onto the retina by changing curvature and corresponding refractive power. Investigators have long sought to understand the mechanism of accommodation in terms of interactions of the constituent tissues, which recently has been aided by biomechanical modeling. Such models depend heavily on accurate measurements of tissue mechanical properties and seek to predict stresses and strains. A critical component of the accommodative apparatus is the lens capsule, a bag-like membrane that encapsulates the lens nucleus and cortex and mediates tractions imposed onto this structure by the ciliary body. In addition to this physiologic process during normalcy, the lens capsule also plays a fundamental role in cataract surgery; a procedure that involves three basic steps: a quarter of the anterior lens capsule is removed via the introduction of a continuous circular capsulorhexis (CCC), the lens is broken up and suctioned out, and an artificial intraocular lens (IOL) is placed within the remnant capsular bag. Although novel IOL designs have decreased post-surgical complications, they currently lack the important feature of accommodation. Therefore, mechanical analysis of the lens capsule will allow for an understanding of its interaction with an implant that may further assist in the design of future accommodating IOLs (AIOLs). Here, we report a novel experimental approach to study in situ the regional, multiaxial mechanical behavior of both normal and diabetic human anterior lens capsules. Furthermore, we use these data to calculate material parameters in a nonlinear stress-strain relation via a custom sub-domain inverse finite element method (FEM). These parameters are then used to predict capsular stresses in response to imposed loads using a forward FEM model.

Abstract:
The aqueous humor (AH) provides oxygen and nutrients for the avascular ocular tissue specifically, the cornea and lens. AH is secreted by the ciliary body into the posterior chamber, passes through pupil, and drains into the anterior chamber (Fig. 1a). Resistance to the aqueous outflow generates the intraocular pressure (IOP), which is 15–20 mmHg in the normal eyes.

Abstract:
In this paper, we propose analytical and numerical experiments to investigate the feasibility of a wireless photonic sensor for measuring the intraocular pressure (IOP). The sensing element is a polymeric cavity embedded into a thin layer of biocompatible material integrated to a soft contact lens. The sensor concept is based on the morphology dependent resonance (MDR) phenomenon. Changes in the eye pressure perturb the micro-cavity morphology, leading to a shift in the optical modes. The IOP is measured by monitoring the shift of optical resonances. The sensor-light coupling is made through the evanescent field by using an optical prism. Therefore, the sensor can be powered and monitored wirelessly by using frustrated total internal reflection (FTIR) of a polymeric dielectric cavity. Usually, micro-optical cavities exhibit a very high quality factor Q; thus, sensors based on MDR phenomenon exhibit high resolution. Therefore, by recording tiny variations of IOP is possible to gain more knowledge about the start, comportment, and evolution of glaucoma disease.

Abstract:
The purpose of this retrospective study is to measure machine learning models' ability to predict glaucoma drainage device (GDD) failure based on demographic information and preoperative measurements. The medical records of sixty-two patients were used. Potential predictors included the patient's race, age, sex, preoperative intraocular pressure (IOP), preoperative visual acuity, number of IOP-lowering medications, and number and type of previous ophthalmic surgeries. Failure was defined as final IOP greater than 18 mm Hg, reduction in IOP less than 20% from baseline, or need for reoperation unrelated to normal implant maintenance. Five classifiers were compared: logistic regression, artificial neural network, random forest, decision tree, and support vector machine. Recursive feature elimination was used to shrink the number of predictors and grid search was used to choose hyperparameters. To prevent leakage, nested cross-validation was used throughout. Overall, the best classifier was logistic regression.

Abstract:
Biomechanics of optic nerve head (ONH) has attracted increasing attention in recent years due to its association with ganglion cell damage and tissue remodeling resulted vision impairments [1, 2]. The ONH is exposed to both intraocular pressure (IOP) and intracranial pressure (ICP), separated by the lamina cribrosa (LC) which is regarded as the primary site of axonal injury in glaucoma[3]. The elevated IOP was widely acknowledged as a major risk factor for glaucoma. However, a large number of glaucoma patients never have an increase in IOP [4]. In studies that have looked at lumbar puncture (LP) data, patients with open-angle glaucoma were found to have lower ICPs than non-glaucomatous controls[5]. It suggests that higher translaminar pressure difference across the LC rather than IOP alone may have an important role in the pathogenesis of ONH damage. There were few computational models had been established to investigate the ICP’s role on ONH, such as Ethier et al. found elevated ICP could induce decreased strain within LC using finite element model[6]. However, less experimental data are available for delineating the role of ICP on the behaviors of LC. In this work, we present one dataset from LP patients and reconstruct its two-dimensional computational model of the ONH based on the patient’s images to delineate the role of ICP on ONH mechanics. The changes of LC depth, BMO width and papillary height were compared between the simulation and clinical dataset. The maximum principal strain of LC was calculated to reinforce its link with mechanosensitive cells in ONH.

Abstract:
Disturbances of the stromal microstructure occurring in refractive surgical procedures may create unexpected and undesired changes to the vision quality of the eye. Examples of common procedures which can profoundly alter the integrity of the stroma include laser ablation techniques such as Laser in situ keratomileusis (LASIK) for treating myopia, hyperopia and astigmatism, scleral incisions for lens extraction in cataract surgery and conducting keratoplasty (CK) for the treatment of hyperopia and presbyopia. The stroma is the primary load-carrying layer of the cornea and in the normal eye it is in a state of tension resulting from the intraocular pressure (IOP). When a surgical procedure disrupts the stromal tissue, the stresses in the tissue will be redistributed inducing what may be called the biomechanical response of the tissue to the surgical procedure. In the case of LASIK and CK, for example, surgeons wish to change the optical power of the cornea by reshaping the anterior surface. Biomechanically induced deformations may cause the achieved power to deviate from the planned correction and may also introduce aberrations in the resulting optical path. In contrast, in cataract surgery, surgeons may wish to preserve the original power of the cornea and in this case biomechanical deformations may defeat this objective.
