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 s

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 com

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

A few years ago, the goal of cataract surgery was simply removal of an opaque crystalline lens. Nowadays, clear lens extraction is used in everyday clinical practice in order to correct refractive errors, especially presbyopia. Different intaocular lens (IOL) designs have been proposed, such as monofocal IOLs with monovision or multifocal IOLs. Accommodative IOLs are considered one of the greatest accomplishments in ophthalmology today.

Over the last several decades, there has been breakthrough in cataract surgery. The rate of intraoperative complications was minimized. One of the most common complications remained the intraocular lens (IOL) dislocations due to inadequate capsular bag support. Thus, the search for an effective and safe method of the IOL fixation in the absence of adequate support of the lens capsule continued to be one of the major problems in anterior segment surgery. This review was devoted to the main methods of correction of intraocular lens dislocation and aphacia.

Abstract:

We present a rare case of bilateral pseudoexfoliative deposits on both intraocular lens (IOL) implants in an 83-year-old woman with no other associated pathology, 5 years after cataract surgery. Pseudoexfoliation syndrome is the most common cause of secondary open-angle glaucoma worldwide and these deposits are usually found on the natural lens. The fact that pseudoexfoliative deposits have been found on IOL implants implies the need for a thorough examination in pseudophakic patients, for it could be the only sign of secondary glaucoma.

Abstract:

Refractive lens exchange (RLE) still has a role in young age with anisometropia, or in an eye that is anatomically not suitable for phakic intraocular lens (IOL) implantation or in high hypermetropia. Furthermore, in the presence of water vacuoles in the crystalline lens above the age of 40, it is recommended to perform RLE rather than phakic IOL implantation. Multifocal refractive IOLs are designed with several optical zones on the IOL. Apodised diffractive multifocal IOL has gradual diffractive steps on the IOL implant that create a smooth transition between focal points. RLE is a surgery wi

The effect of the diameter of an intraocular lens (IOL) implanted in enucleated porcine eyes on the intraocular pressure induced by scleral depression was investigated. Two IOLs of 6 mm and 7 mm optic diameter were implanted. The intraocular pressure (IOP) was monitored during scleral depression by a transducer placed in the midvitreous through a sclerotomy at 6 o’clock. The area under the curve (AUC) of the IOP changes from the beginning of the indentation to the point when the peripheral retinal surface was observed through the IOL optics was measured.

Abstract:

Purpose: Achieving the desired post-operative refraction in cataract surgery requires accurate calculations for intraocular lens (IOL) power. Latest-generation formulae use anterior-chamber depth (ACD)—the distance from the corneal apex to the anterior surface of the lens—as one of the parameters to predict the post-operative IOL position within the eye, termed the effective lens position (ELP). Significant discrepancies between predicted and actual ELP result in refractive surprise. This study aims to improve the predictability of ELP. We hypothesise that predictions based on the distance fro

Since the introduction of phacoemulsification, cataract surgery has evolved remarkably. The use of premium intraocular lenses (IOLs) (aspheric, toric, multifocal), refractive lens exchange and patients after refractive surgery procedures require extremely precise clinical measurements and IOL calculation formulas to achieve desired postoperative refraction. For many years, ultrasound biometry has been the standard for measurement of ocular parameters. The introduction of optical biometry (fast and non-invasive) has replaced ultrasound methods and is now considered as the clinical standard for
