Role Of Phakic Intraocular Lens In Stable Corneal Ectatic Disorders

The purpose of this study was to report the results of Phakic IOL for refractive correction in stable corneal ectatic disorders.

.

This is a case series and literature review.

This study included three patients with corneal ectatic disorders. The first patient was a 26-year-old male with keratoconus who had undergone corneal collagen cross-linking (CXL) 3 years ago and his disease has been stable since then. The second patient was a 30-year-old male with pellucid marginal degeneration (PMD) whose disease had been stable for 3 years. The third patient was a 32-year-old male with keratoconus whose disease had been stable for 4 years. All three patients were implanted with Visian Toric Implantable Collamer Lens (TICL) (STAAR Surgical, Nidau, Switzerland).

On the first post-operative day, all three patients had uncorrected vision of ≥6/9 in both of their eyes. Vaulting was adequate (250-750 microns) in each eye. No complications were noted in any case. The visual acuity and topography were stable on further follow-ups for upto several months in each patient.

Phakic IOLs are a great option for refractive correction in patients with corneal ectatic disorders. However, the topographic and refractive stability of these disorders must be ensured before planning the surgery.
