The clinical outcome of implantable collamer lens in corneal ectasia post astigmatic keratotomy.

INTRODUCTION

Implantable collamer lens (ICL) is a posterior chamber phakic intraocular lens. It is usually indicated for high refractive error correction that cannot be treated by laser vision correction due to physical limitations.

CASE PRESENTATION

39 years old male with a past ocular history of keratoconus underwent astigmatic keratotomy followed by crosslinking in both eyes a couple of years later due to signs of corneal ectasia progression.

DISCUSSION

Astigmatic keratotomy is highly unpredictable in keratoconus patients as it might induce progressive irregular astigmatism. After confirming the stability of refraction and corneal topographic reading for the past couple of years. We insert EVO visian V4c ICL 13.2 manufactured by STAAR surgical company under topical anesthesia sequentially to both eyes.

CONCLUSION

Our case depicts the successful use of ICL in ectatic cornea post-astigmatic keratotomy with an excellent outcome. Further study with large case series and long follow-up is recommended to evaluate the efficacy and safety profile.
