Corneal collagen cross-linking followed by phacoemulsification with IOL implantation for progressive keratoconus associated with high myopia and cataract.

PURPOSE: To evaluate the visual and topographic outcomes of a two-stage approach treatment for progressive keratoconus (KC) associated with high myopia and cataract.

METHODS

Two patients, a 50-year-old man and a 54-year-old woman with high myopia (spherical equivalent greater than -10D), cataract, and progressive KC with poor spectacle-corrected vision and contact lens intolerance underwent a 2-stage approach treatment: first corneal collagen cross-linking (CXL) followed after at least 6 months by phacoemulsification with intraocular lens (IOL) implantation in both eyes.

RESULTS

In both patients after a mean follow-up of 3.5 years (from 2 to 4) uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), and corneal topography pattern improved in both eyes, and the patients were satisfied with the visual improvement and happy with tolerable glasses.

CONCLUSION

This 2-stage approach reported no complications and was effective in improving visual acuity and corneal patterns in patients with high myopia, cataract, and progressive KC.
