BACKGROUND The present study aimed to evaluate the degree of anterior capsule contraction (capsulorhexis contraction) with three different single-piece, hydrophilic acrylic intraocular lenses (IOLs). METHODS Patients were prospectively randomized to be implanted with one of three types of IOLs during cataract surgery: the Ophtec Precizon (IOL A), the Lucid Korea Microflex (IOL B), and the Car...

The tilt and decentration of intraocular lens (IOL) result in defocussing, astigmatism, and wavefront aberration after operation. The objective is to give a method to estimate the tilt and decentration of IOL more accurately. Based on AS-OCT images of twelve eyes from eight cases with subluxation lens after operation, we fitted spherical equation to the data obtained from the images of the ante...

In this study we evaluate the visual outcomes, safety, efficacy, and stability of implanting of second sulcus intraocular lens (IOL) to correct unsatisfied ametropic patients after phacoemulsification. Methods. Retrospective study of 15 eyes (15 patients) underwent secondary intraocular lens implanted into the ciliary sulcus. The IOL used was a Sensar IOL three-piece foldable hydrophobic acryli...

An 86-year-old man with a Binkhorst 2-loop intraocular lens (IOL) that was implanted in the pupillary sphincter 33 years earlier was examined. The pupil of the implanted eye with the Binkhorst IOL was irregular and the eye had pseudoexfoliation (PEX) syndrome. Pupillary erosion resulted from rubbing of the IOL edge against the pupillary sphincter with PEX material. The IOL was removed because o...

I f it were possible to adjust the refraction of a pseudophakic eye by means of an adjustable posterior chamber intraocular lens (PC/IOL), subjective comfort or visual function would be improved. This is especially true in children. Several approaches to create an adjustable intraocular lens (IOL) are currently under study. This field is still in an early stage of its evolution. The *Acri.Tec A...

Treatment options for symptomatic subluxated or dislocated IOLs include observation; and repositioning, removal, or exchange of the IOL. We describe a surgical technique of trans-scleral suture fixation for subluxated bag-IOL complex. A 29 year old male; known case of bilateral recurrent tubercular panuveitis underwent left eye phacoemulsification with three piece hydrophobic acrylic IOL implan...

AIMS To investigate the adhesion characteristics of several intraocular lenses (IOLs) to the simulated and rabbit lens capsule. METHODS Adhesive force to bovine collagen sheets was measured in water with polymethylmethacrylate (PMMA), three piece silicone, and acrylic foldable IOLs. In rabbit eyes, phacoemulsification and IOL implantation were performed. Three weeks later, adhesion between th...

INTRODUCTION Iatrogenic pigment dispersion syndrome generally originates from a repetitive, mechanical trauma to the pigmented posterior epithelium of the iris. This trauma can arise after intraocular surgery, most commonly due to an abnormal contact between the intraocular lens (IOL) and the iris. Whether surgical removal of this primary insult can lead to a successful intraocular pressure (IO...

Background. To evaluate the clinical efficacy of suture fixation of foldable intraocular lens (IOL) in ciliary sulcus guided by ultrasound biomicroscopy (UBM). Methods. Thirty-five eyes of 32 cases needing suture fixation of foldable IOL in ciliary sulcus in our hospital were collected and divided into two groups: group A and group B. In group A, UBM was performed on 19 eyes of 17 cases before ...

PURPOSE To evaluate the difference in the effect of 2 speeds of intraocular lens (IOL) insertion on the clear corneal wound structure. SETTING Ouchi Eye Clinic, Kyoto, Japan. DESIGN Prospective randomized clinical trial. METHOD Eyes that had phacoemulsification and Acrysof IQ IOL implantation using a screw-plunger type injector were randomly divided into 2 equally sized groups as follows:...
