Correction Of Aphakia In Children Using A Modified Technique For Retropupillary Iris Supported Iol (7 Year Study)

To assess the efficacy, stability and safety of correction of aphakia in children using a modified technique for retropupillary iris supported iol

The Memorial Institute For Ophthalmic Research (MIOR)

case series study of 50 eyes of 30 pts aged between 4-15 y  with Fu period ranges from 2 y- 5 y

 The inclusion criteria : aphakia with insufficient capsular support, sufficient iris tissue , no history of uveitis.

Excluison Criteria : presence of capsularsupport , aniridia, sever iris atrophy 

PreOperative :full ophthalmic examination 

post operative: follow up the stability of the iol in its place , areas of iris atrophy and ref

This modified technique depending on that while I am fixating the claw in the iris ,I perforate the iris with one side of the claw to keep one side of each claw anterior to the iris, this will be more safe especially for children that this will prevent the IOL from dropping in vitreous with trauma or with iris atrophy 

study included 30 patients, Their age ranged from 4 to 15 y with mean age of 6.73 ± 5.22 years.

 100% of eyes showed improvement in UCVA, BCVA, stable IOL in their places (no dropped iol ,no decentered iol, no dislocted iol).

preop. UCVA ranged from 0.01 to 0.05, with a mean of 0.025 ± 0.028. The preop. BCVA ranged from 0.4 to 0.7, with a mean of 0.62 ± 0.071. 

 postoperative :  UCVA ranged from 0.3 to 0.7, with a mean of 0.46 ± 0.082 , BCVA ranged from 0.5 to 0.9, with a mean of 0.86 ± 0.13 .

Pre-operative sphere (+6.00 to +10.0) that significant changed post-operatively to (+1.00 to + 2.00).

 post- op complications:  7  eyes showed mild corneal edema, 5 eyes had transient IOP elevation more than 20 , 5 eye had AC inflammatory reaction.

Retropupillary iris claw IOL is the best choice of correction of aphakia in children 

 This modification I did in the original technique will make the use of this IOL more safe  in children even if iris atrophy occured or trauma to the eye , the part of iol in front of the iris tissue will prevent iol from dropped in the viterous.
