  1. Surgical Peripheral Iridectomy In Implantable Collamer Lens Procedure in Brown Irides Dr. Prasad Kasu Reddy Maxivision Eye Clinic Hyderabad, India

  2. STUDY PURPOSE • STAAR Surgicals recommended 2 Yag Laser • Peripheral Iridectomies pre-operatively and 2 portal incisions in ICL procedure • AIM • To use one portal incision at 12 ‘O’ clock for manipulating the ICL and same portal incision for surgical PI • To analyze surgical iridectomies in ICL procedure • in patients with brown iridies • To discuss the method of Surgical PI

  3. STUDY DESIGN Source : Maxivision Eye Clinic, Hyderabad, India No. of Cases Studied : 109 eyes from 60 patients Study Period : July 2005 to September 2007 Clinical History : High Myopes with low pachymetry with mean Anterior chamber Depth of 2.8mm

  4. METHODOLOGY One Portal Incision (12 o’ clock) ICL Manipulation Surgical PI ( after constricting the pupil with pilocar) Gently pulling the iris through the same port ( using Hoskins forceps) Iridectomy ( using Vannus scissors) (An age old technique) Incomplete PI Completed PI (Left with a posterior (piece-meal removal of smooth pigmented layer) pigmented layer) Irrigation Aspiration

  5. POST SURGICAL OBSERVATIONS • Clinical examination of all the patients was done on : • - 1st post op day - 6 months post op • - 1st week post op - yearly examination • - 4 week post op • - 3 months post op • All PI’s were patent • Intra Ocular Pressures ranged from 16-26mm of Hg • 10 eyes showed elevation of Intra Ocular Pressure

  6. RESULTS • The increase in Intra Ocular Pressure was transient, • as these patients were found to be steroid responders • These patients were treated with anti-glaucoma • medication and switched over to voveron optha that • controlled the IOP

  7. In Brown Iridies Surgical PI Thorough I & A 2 Yag Laser PI’s Can Disperse pigment No Pigment Dispersion No block, Trabecular meshwork Block trabecular meshwork Chronic Rise in IOP No rise in IOP

  8. CONCLUSION One portal manipulation of ICL and surgical peripheral iridotomy is advantageous and effective.
