Comparison Of Scleral-Fixated Posterior Chamber Intraocular Lens Implantation And Posterior Iris- Claw Intraocular Lens Implantation In The Treatment Of Aphakia With Insufficient Capsular Support


Aim : To compare the outcome of scleral-fixated posterior chamber intraocular lens (PCIOL) with retro-pupillary fixation of iris-claw intraocular lens (IOL) in the treatment of aphakic eyes with insufficient capsular support as regard to the safety, complications and visual outcomes of the procedure. Methods : A total of 40 patients were divided into 2 equal groups : 20 eyes were implanted with scleral fixated PCIOL and 20 eyes were implanted with irisclaw IOL. Postoperative corrected distance visual acuity (CDVA), intraocular pressure (IOP) & postoperative complications were compared between the 2 groups during the followup period on day 1, 7 days, 14 days,1 month and after 3 months. Results: On the first postoperative day, the CDVA ranged from 0.06 to 0.32 in the iris-claw group, with a mean of 0.26 ± 0.108 and it ranged from 0.06 to 0.18 in the scleral- fixated group with a mean of 0.12±0.044; there was a statistically significant difference between the groups. After the 3 months postoperatively, the CDVA ranged from 0.25 to 0.8 in the irisclaw group with a mean of 0.56±0.25 and it ranged from 0.15 to 0.6 in the scleral-fixated group with a mean of 0.46±0.16; there was no statistically significant difference between the 2 groups. On the day 1 postoperatively the mean intraocular pressure in the irisclaw group was 15.46±2.48 mmHg whereas in scleral fixating IOL group it was 19.24±3.86 mmHg with a statistical difference between 2 groups. Iris claw groups showed higher rates of pupillary distortion, anterior chamber reaction and cystoid macular oedemapostoperatively. Whereas corneal oedema, vitreous haemorrhage and retinal detachment were higher in the scleral fixation group.
