Phakic Icl In The Management Of Residual Refractive Error In Pseudophakic Eye.

In this study we will evaluate the outcomes of toric implantable collamer lens (ICL) in the management of residual astigmatism in pseudophakic eyes

Bharti eye hospital, New Delhi, India

Patients with pseudophakia with  residual astigmatism of -3.5 to -6 D were included. They underwent piggyback toric ICL implantation in that eye. Uncorrected distance visual acuity (UDVA), uncorrected near visual acuity (UNVA), Best corrected visual acuity (BCVA), contrast sensitivity, and Visual Function Index (VFI) were evaluated at 1 day, 1 week,1 month,3 months and 6 months postoperatively. Intraocular pressure (IOP), vault height, anterior chamber reaction and graft endothelial cell count was measured each visit.

15 eyes of 15 patients were included in the study. Mean age was 62.66 years. The mean preoperative spherical equivalent was -6.11 D (-4.75 to -8 D) improving to -0.80 D postoperatively (0.25 to -1.5 D). Mean UDVA was 6/12P and mean UNVA was N8 in toric ICL implanted eyes. Mean BCVA was 6/12.  Contrast sensitivity was better with toric ICL than preoperatively with glasses. Mean IOP was 14.6 mm Hg on non-contact tonometry. 93.33% of patients were satisfied at 6 months postoperatively. No adverse effects like increased intraocular pressure, decreased endothelial count, decreased vault height or anterior chamber reaction were seen in follow up period.

Toric ICLs were found to be safe and effective piggyback intraocular lenses (IOLs) in pseudophakic eyes for management of residual refractive error and astigmatism and show a good visual outcome for distance and near vision with good patient satisfaction.
