AcrySof Toric IQ Post-Market Clinical Study

Patients will be examined pre-operatively to up to 3 years post-operatively. One eligible eye will be selected as a target eye for efficacy analysis. If both eyes are eligible, the eye in which the IOL is implanted first will be selected as the target eye.

Phase N/A

A Study Comparing Two Monofocal Aspheric Hydrophobic Acrylic Intraocular Lenses: the Alcon CLAREON and the Abbott Medical Optics PCB00

This is a bilateral randomised controlled study to compare visual performance, refractive outcome, forward light scatter, patient satisfaction and objective measurement of glistenings following insertion of two monofocal, aspheric, hydrophobic acrylic intraocular lenses (IOLs). A new product is compared with an established one.

Phase N/A

The Incidence of Glistenings in the 2017 Intraocular Lenses Made by Alcon and Abbott Medical Optics

Glistenings are tiny, clear sparkling, fluid-filled microvacuoles that form within a lens after it has been placed in the eye. Glistenings are seen in all lenses but certain lenses develop a higher number of glistenings than others. The effect of glistenings on patients' visual functioning is largely unknown. The occurrence ...

Phase N/A

A Study to Assess the Clinical Outcomes of Surgical Phaco Segmentation Techniques in Patients Undergoing Cataract Surgery

The purpose of this research study is to evaluate the clinical outcomes of different cataract surgical techniques for lens fragmentation in subjects undergoing routine cataract surgery.


A Clinical Assessment of the Full Range of Functional Vision With Three Tecnis Multifocal IOL 1-Piece Models in Bilateral Cataract Extraction

This will be a multi-center, parallel comparison clinical study design with two treatment groups. One hundred (100) qualified study patients will receive a +2.75D (ZKB00) Tecnis Multifocal 1-Piece IOL in their dominant eye. Of these study patients, 50 patients will receive the +3.25D (ZLB00) Tecnis Multifocal 1-Piece IOL in their ...

Individual vs Cohort Long Distance Advising for Mental Care for Congenital Cataract Guardians

Congenital cataract (CC) is the leading cause of reversible blindness during childhood, which appears at birth or during the first decade of life. Nowadays, doctors put mental health at a prior place and pay more attention to the psychological problems of ill kids' parents. In our research, we try to ...

Phase N/A

Effect on the Vitreous of the Not Complicated Surgery of the Cataract to the Emmetropic Patient

This study evaluates the association between surgery of the cataract and posterior vitreous detachment, in the emmetropic patient, by comparing eyes operated with eyes not operated in the same group of patients

Phase N/A

Dysfunctional Lens Index Serves as a Novel Surgery Decision Maker for Age-related Cataracts

Each patient received a comprehensive eye examination, including corrected distance visual acuity (CDVA) preoperatively and the day after surgery, subjective refraction, slit-lamp evaluation, noncontact tonometry (TX-F; Cannon, Tokyo, Japan), and dilated fundus examination. According to the surgery decision made by the three surgeons based on the slit lamp biomicroscopy and ...

Phase N/A

Comparison of Clinical Outcomes on Trifocal IOLs FineVision POD F GF and FineVision POD F in Asian Eyes

This is a prospective, randomised, controlled, single-surgeon, single-center clinical study whereby patients undergoing routine cataract surgery will have bilateral implantation of trifocal intraocular lenses. The patients will either be implanted with the hydrophobic IOL FineVision POD F GF or the hydrophilic IOL FineVision POD F (both lenses: (PhysIOL, Lige, Belgium). ...

Phase N/A

Two Different Cataract Surgical Procedures to Prevent Posterior Capsule Opacification

A prospective, randomized controlled study of 240 eligible patients will been enrolled. Two eyes of each patient were assigned randomly to two groups respectively: Group I; anterior lens capsule is conventionally not reserved after continuous curvilinear capsulorhexis, while in Group II, anterior lens capsule is innovatively reserved and attached onto ...
