Abstract Details



Purpose:

To assess the efficacy and stability of simultaneous topography-guided photorefractive keratectomy (PRK) and crosslinking (Athens protocol) after intacs implantation in managing keratoconus

Setting:

IMC, Dubai, UAE

Methods:

We included 14 patients (22 eyes) with keratoconus that required visual enhancement 12-18 months after Intacs Sk implantation . All patients underwent topography-guided PRK to be followed immediately by collagen crosslinking. The laser optical zone diameter was set to 5-5.5 mm. Corrections targeted 70ḟ10% of cylinder error and 70% of sphere error.

Results:

Eyes were examined after a minimum 6-month follow-up. The mean preoperative keratometric reading (45.75 D) was reduced to 44.04 D (P<0.001). The mean spherical equivalent was reduced from -8.89ḟ7.71 to -0.93ḟ0.7 (P=0.003). The mean uncorrected visual acuity improved from 1.24ḟ0.49 to 0.52ḟ0.20 logMAR. The mean corrected visual acuity improved from 0.68ḟ0.25 to 0.324ḟ0.16 logMAR. Central corneal haze appeared in some eyes postoperatively, but gradually faded over 3 months.

Conclusions:

Athens protocol improved and stabilized visual performance in patients implanted with Intacs Sk in keratoconus. These results justify a future, large-scale study with a longer follow-up.
