MODIFIED TECHNIQUE FOR RETROPUPILLARY IRIS SUPPORTED IOL

to asses the efficacy, stability and safety of implanting retropupillary iris supported iol  using this modified technique espically in children

memorial institute for ophthalmic research

Prospective interventional case series study of (10) eyes of 10 patients (7 males and 3 female) aged between 4-62 years with unilateral or bilateral aphakia without capsular support.Patients were done by 1 surgeon in the memorial institute for ophthamic research (MIOR) with follow up period ranges from 6 m -2years.Inclusion Criteria : patients with unilateral or bilateral aphakia without capsular support , no hoistory of uveitis.Excluison Criteria : presence of capsular support , aniridia, sever iris atrophy or iris laceration that cannot be repaired.Surgical Technique : 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 viterous with trauma or with iris atrophy ( this technique showed in the videos of surgeries).PreOperative :full ophthalmic examination spiecally BCVA and absence of capsular support and presence of iris support.post operative: follow up the stability of the iol in its place , areas of iris atrophy and refraction of the patient .

100% of eyes showed improvement in UCVA, BCVA, stable IOL in their places (no dropped iol ,no decentered iol, no dislocted iol). UCVA : Pre-operative range from (1/60-3/60) improved post-operative to (0.3-0.7).BCVA : Pre-operative range from (0.4- 0.7) improved post-operative to ( 0.5-0.9).Refraction : no significant change in cylinder between pre and postoperatve cylinder, pre-operative sphere (+6.00 to +10.0) with  significant changes post-operatively that post operatve sphere (+1.00 to + 2.00). 

 

Retropupillary iris claw IOL is the best choice of correction of aphakia. This modification I did in the original technique will make the use of this IOL more safe especially 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.
