Implantable collamer lens for correction of ametropia in eyes with corneal scarring.

CASES: Two cases are reported in which implantation of a collagen copolymer phakic intraocular lens (implantable collamer lens) corrected refractive errors in eyes with corneal scarring. A previous accident, in both cases, resulted in a central linear scar on the surface of the cornea of one eye. In the first patient, a corneal scar was visible in the left eye. The distance corrected visual acuity was 0.3 (-7.75 -4×160°). An uncorrected distance visual acuity of 0.25 was obtained by implanting an implantable collamer lens. In the second patient an oblique corneal scar was visible in the right eye. The distance corrected visual acuity was 0.25 (-8.75 -1.25×8°), and after implantation of the implantable collamer lens, uncorrected distance visual acuity was 0.25.

DISCUSSION: The indications of the implantable collamer lens should be reviewed and possibly expanded.
