Evaluation of Cataract Surgery Outcome

The purpose of this study is to evaluate the visual outcome of the cataract surgery, including best uncorrected and corrected visual acuity, spherical equivalent, wavefront aberration and other measurements.

Phase N/A

Non-genetic Risk Factors of Congenital Cataracts

Prevention and treatment of the reversible childhood blindness, including congenital cataracts (CC), has been listed as a significant component of the international programme "VISION 2020 - the Right to Sight" launched by WHO in 1999. However, there is still a lot of unsolved problems regarding to CC, especially in developing ...

Phase N/A

IOL Implantation After KAMRA Inlay Removal

This will be a prospective study in which no more than 20 subjects will be implanted with IC-8 IOL following the removal of the KAMRA inlay. The refractive target of the IC-8 eye will be -0.75 D MRSE. Subjects will be screened for eligibility and consented before enrolled. Following enrollment, ...

Phase N/A

Evaluation of Macular Changes After Intracameral Moxifloxacin for Prevention of Endophthalmitis

Title Evaluation and Comparison of Macular and Choroidal Thickness after Intracameral Moxifloxacin for Prevention of Postcataract Endophthalmitis Purpose The objective of this study is to evaluate if the using of intracameral moxifloxacin cause changes in macular and choroidal thickness. Methods A randomized clinical trial will be conducted in the Hospital ...


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

Clinical Study to Compare Visual Performance of Two Trifocal IOLs

This is a prospective, randomised, controlled, single-surgeon, single-center post-market clinical follow up 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. The primary ...

Phase N/A

Morphologic and Biometric Characteristics of Preexisting Posterior Capsule Defects in Congenital Cataracts During the First Year of Life

This retrospective study reviewed infants (1 years old) with CC who were undergoing cataract extraction without IOL implantation at the Eye Hospital of Wenzhou Medical University, Hangzhou, China. CC patients with preexisting PCDs were placed in Study group, while CC patients with intact posterior capsule were included as controls. The ...

Phase N/A

Intraocular Lens Power Calculation After Laser Refractive Surgery Based on Optical Coherence Tomography

This study is about a new imaging method to study the front part of the eye. This imaging method is called Optical Coherence Tomography (OCT) which provides detailed cross-sectional (layered) views of structures in the eye. The OCT system scans a beam of light across the eye to take a ...

Phase N/A

Surgical Treatment of Concurrent Cataract and Primary Pterygium

Pterygium is known to induce with-the-rule astigmatism. The corneal curvature along the long axis of the pterygium body is flattened. The excision of pterygium will result in steepening of the cornea and reduction of astigmatism. Therefore, the effect of pterygium excision on intraocular lens (IOL) power calculation has been examined ...

Phase N/A

Hypnosis for Eye Surgery

Perioperative stress for cataract surgery in the elderly is considerable even in the absence of pain. For these patients with a high comorbidity level, the perioperative situation comprising factors such as uncomfortable positioning, dull ambience, face cover, poor sedation, and anxiety might not only reduce intraoperative compliance but induce cardiac ...
