A Comparative Study of Surgical Outcome Between Iris Claw and Scleral Tuck Intraocular Lens in Primary Cataract Surgery by Phacoemulsification in A Tertiary Care Center- A Study Protocol
ABSTRACT
Background:
Age-related cataract is the major cause of the worldwide diminution of vision, affecting around 20 million people. The lens has a thin and transparent capsule that covers the lens completely. The posterior pole of the lens is the thinnest part of the capsule. Cataract surgery can lead to various complications, one of which is posterior capsular rupture. If sufficient posterior capsule remains intact after rupture, implanting an intraocular lens (IOL) in the ciliary sulcus is technically possible. Aphakia caused due to trauma or complicated surgery, there may be insufficient capsular support to place a posterior chamber intraocular lens (PCIOL) in the sulcus. The aim of the study was to evaluate surgical outcome between iris claw & scleral tuck intraocular lens in the primary cataract surgery via phacoemulsification.
Objective:
1. To determine the lens-induced astigmatism between the Scleral tuck lens and the Iris Claw lens. 2. To analyse the intraoperative challenges and complications associated with the Scleral tuck lens and Iris Claw lens. 3. To evaluate the post-surgical complications between the Scleral tuck lens and the Iris Claw lens.
Methods:
A hospital-based, open-label randomized control trial will compare iris-claw and scleral tuck lenses in patients after cataract surgery. This will be conducted at AVBRH, Sawangi. In this study, data will include preoperative, intraoperative, and postoperative outcomes
Results:
The research is expected to show that both the iris-claw and scleral tuck lenses will improve the visual outcomes in patients included in the study. However, iris-claw lenses might demonstrate fewer intraoperative complications and quicker surgical time along with better stability. On the contrary, scleral tuck lenses might show comparable visual improvement. Nevertheless, it slightly has higher rates of postoperative complications and technical challenges.
Conclusions:
The conclusion will be made after the completion of the study. Clinical Trial: The study is registered with Clinical Trial Registry of India Approval Number - CTRI/2025/03/083687 (Dated- 28/03/2025)
