PURPOSE To evaluate whether the Tecnis Z9000 intraocular lens (IOL) (Pfizer) with a modified prolate anterior surface provides better quality of vision than a conventional spherical IOL. SETTING Oregon Eye Institute, Eugene, Oregon, USA. METHODS Patients presenting for cataract surgery who were randomly assigned to receive a Tecnis Z9000 IOL (Pfizer) or a Sensar OptiEdge AR40e IOL (AMO) in ...

OBJECTIVE To evaluate the prevalence, indications, and factors associated with successful induction of labor (IOL), and maternal and neonatal outcomes. METHODS All women booked for IOL at King Khalid University Hospital, King Saud University, Riyadh, Kingdom of Saudi Arabia from April 2010 to March 2011 were included. The characteristics of women who had successful IOL were compared to those ...

PURPOSE To establish a fully human in vitro culture model with which to test the putative effects of intraocular lens (IOL) designs in preventing posterior capsule opacification (PCO) after cataract surgery. METHODS A sham cataract operation was performed to prepare human capsular bags from donor lenses. In one capsular bag of a donor pair, an intraocular lens (PMMA round-edge IOL or acrylic ...

Purpose To compare surgically induced astigmatism (SIA) and refractive outcomes between two operation methods for late in-the-bag IOL dislocation. Methods In this prospective, randomized, parallel-group clinical trial, 104 patients (eyes) were assigned to IOL repositioning by scleral suturing 1.5- to 2-mm posterior to limbus (n = 54) or IOL exchange with a retropupillar iris-claw IOL using a ...

BACKGROUND Intraocular lymphoma (IOL) is a rare malignant lymphoma that most closely resembles a diffuse large B-cell lymphoma, and it is a subtype of primary central nervous system lymphoma (PCNSL). IOL is located inside the eye in the retina, uvea, and/or optic nerve. We retrospectively analyzed IOL patient data to identify treatment patterns and survival rates in Korea. METHODS Cytological...

PURPOSE To evaluate blue-light attenuation in eyes with a tinted intraocular lens (IOL) or an untinted IOL. SETTING Department of Ophthalmology, University Hospital of Crete, Crete, Greece. DESIGN Comparative case series. METHODS Patients had lens extraction and implantation of an Acrysof Natural tinted or Tecnis ZA9003 or Softec III untinted acrylic IOL. The luminance ratio of green (530...

Background: this retrospective study aimed to analyze the results of combination Haigis formula and total keratometry (TK) in calculating IOL power eyes with previous corneal refractive surgery. Methods: TK value provided by Master 700 (Carl Zeiss Meditec) was introduced into formula; mean prediction error (PE), absolute (MAE), median (MedAE) percentage a PE within ±0.25 D, ±0.5 ±0.75 D ±1.00 w...

BACKGROUND With recent advances in technology and introduction of new intraocular lens (IOL) models, surgeons today have the opportunity to choose from various optical designs, which can influence the postoperative quality of vision. In our laboratory study, we compared the optical quality of three different IOLs that use the identical platform and are produced by the same manufacturer. The stu...

Background: The present study aimed to evaluate and compare the efficacy of toric intraocular lens (IOL) implantation aspheric IOL with steep-axis incision for correcting mild moderate corneal astigmatism in cataract patients.

PURPOSE To compare the contrast sensitivity of an intraocular lens (IOL) with a modified prolate anterior surface (Tecnis Z9000, Pfizer), with 2 standard spherical IOLs (Sensar AR40e Opti-Edge IOL, AMO and AcrySof Natural SN60AT IOL, Alcon). METHODS In this prospective study, 98 eyes of 71 patients received 1 of 3 IOLs at random. After 6 months, best corrected visual acuity, pupil size and co...
