A Review of Modified New Surgical Technique for Trans-Scleral Fixation of Posterior Chamber Intraocular Lenses in Case of Aphakia with Absent or Deficient Posterior Capsule

Abstract

A common complication of trans-scleral fixation of posterior chamber intraocular lenses with prolene suture is high rate of spontaneous dislocation of the IOL due to biodegradation or breakage of suture. This is because of, at the place of suture knots, there is inflammation and continuous irritation, which leads to scleral melting and suture disintegration in due course of time. We report a new technique of suture tying and burying the knot of prolene suture in the scleral pocket instead of making a sclera flap and suturing the flap. We also tie the lens eyelet with double suture instead of single suture to ensure maximum post operative stability of lens. We achieved a very good centration and stability of S IOL with this technique. A good aspect was that there was no visible suture knot of any type, either of prolene suture or flap suture. This new technique is good modification of conventional technique to prevent knot and sclera flap related problems.
