Visual outcome and corneal topography after eccentric "shaped" corneal grafts.

PURPOSE

To study the clinical and visual outcome and corneal topography in eyes that underwent full-thickness or lamellar eccentric-"shaped" (biconvex/crescentic) corneal grafts.

SETTING

Tertiary care center in south India.

METHODS

In this retrospective, interventional, noncomparative case series, eccentric-shaped corneal grafts were performed in 10 eyes (10 patients). Biconvex grafts were performed in 7 eyes, and crescentic grafts were done in 3 eyes. The indications for biconvex grafts were peripheral infected corneal ulcer (3 eyes), limbal dermoid (1 eye), squamous cell carcinoma at limbus (1 eye), rheumatoid arthritis-associated peripheral corneal melt (1 eye), and peripheral corneal perforation of unknown etiology (1 eye). Crescentic graft was performed for perforated Mooren ulcer in 3 eyes.

RESULTS

All grafts were tectonically effective. Three grafts developed stromal haze with fine vascularization. Visual acuity was equal to or better than that before surgery in all eyes but one. This eye had deterioration in visual acuity because of progression of cataract. Corneal topography was performed in 5 eyes, which revealed corneal asymmetry but regular central corneal surface.

CONCLUSION

Shaped corneal grafts for peripheral corneal diseases are tectonically viable and result in good visual outcomes.
