Abstract Details


To evaluate safety and recovery of retropupillary fixation of iris-claw intraocular lens (IOL) (Verisyse PMMA IOL, Abbott Medical Optics [AMO], Netherland) in surgical correction of aphakia in microspherophakic eyes where there is no sufficient capsular support


Zagazig University Hospital in Sharkia Governorate in Egypt


Prospective interventional non comparative case series. This interventional case series comprised 17 eyes of 9 microspherophakic patients. Retropupillary fixation of the Verisyse iris claw IOL [AMO] was done in all cases. Surgical time was measured. Corrected distance visual acuity (CDVA), astigmatism, intraocular pressure, tissue reaction, pigment dispersion and stability of IOL were studied 1 day, 3 days, 1 week , 2 weeks, and 1 and 6 months postoperatively.


Eight patients had familial microspherophakia and one patient had Marfan's syndrome. 82% of the cases achieved visual acuity of 6/18 or better. There was no significant change in astigmatism postoperatively. There was no significant inflammatory reaction. Transient elevation of IOP was recorded in two cases in the first week only; One IOL developed iris dis-insertion of one of the haptics and was successfully re-inserted. All the other IOLs were well centered and stable. Mean surgical time of Verisyse IOL [AMO] implantation was (18.0 ± 4.5 min)


Retropupillary fixation of an iris-claw IOL is a safe and effective procedure, provides early visual recovery, and is a time-saving method for correcting aphakia in microspherophakic eyes without sufficient capsular support
