Corneal Endothelial Changes Following Pediatric Cataract Surgery With IOL Implantation

Congenital Cataract SurgeryIOL Implantation1 more

Cataract surgery is known to cause loss of corneal endothelial cells. In adults, it is reported that anywhere between 2 to 15% loss of corneal endothelial cell density occurs following cataract surgery. However, no data is available regarding endothelial changes after cataract surgery with IOL implantation in pediatric eyes. The aim of this study is to prospectively observe changes in endothelial cell density, coefficient of variation and hexagonality following cataract surgery with IOL implantation in pediatric eyes.

A Comparison of 0.5% Loteprednol Etabonate Versus 1% Prednisolone Acetate Following Cataract Surgery...

Intraocular Inflammation

Patients are routinely given steroid eye drops following cataract surgery. This study will compare 2 approved drops:Loteprednol Etabonate versus Prednisolone Acetate Eye drops used following cataract surgery. Patients will be randomly assigned to one drop or the other, and evaluated for inflammation and intraocular pressure as part of the comparison. The study Doctor will be masked as to which drop the patient receives to avoid bias.

Studies of Families With Hereditary Cataracts

CataractCongenital Anomaly

The objective of this study is to discover the genes responsible for the development of hereditary cataracts in families. A cataract is clouding of the lens of the eye that obstructs the passage of light and may impair vision. Information from this study may provide a better understanding of why hereditary cataracts form and perhaps lead to the development of a test that can predict who will likely be affected and to what degree. Patients or family members of patients with inherited cataracts who participate in this study will be asked questions about their family history, especially concerning eye disease or cataracts, and a family tree will be drawn. They will undergo a complete eye examination, including photographs to document the clarity or opacity of the lens. In addition, a small blood sample will be drawn for use in gene mapping studies of inherited cataract.

Age-related Changes of Crystalline Lens Tilt and Decentration: A Swept-source Optical Coherence...

Crystalline CataractLens; Anomaly

230 participants at Eye Hospital of Wenzhou Medical University during June, 2019 and August, 2019 were enrolled in this study. 230 right eyes and 88 left eyes were included for the measurement. All the measurements were performed under non-mydriatic conditions in a dim examination room using the CASIA2 swept-source AS-OCT system.
