Abstract Details

Purpose:

To describe the results obtained after an implantable toric collamer lens (TICL) was used to correct ametropia and irregular astigmatism after corneal scarring due to bacterial keratitis in one eye.

Setting:

Oftalvist Group, Juan Bravo 1, Madrid, Spain.

Methods:

A 23-year old male with bilateral myopia and a corneal paracentral scar on his left eye due to an episode of infectious keratitis (P. aeruginosa) 5 years before, came to our clinic interested in refractive surgery. The scar had a 50% depth and affected half of the visual axis. Best corrected visual acuity with -6.25-2.25 x 83º was 0.4. Topography showed an annular shaped irregular astigmatism with applanation in the centre corresponding to the scar, with a topographic astigmatism of 0.54. The right eye was myopic (-7.25-1.00 x 95º) and suitable for ICL implantation.

Results:

An implantable toric collamer lens (VTICM5, 13.7 mm, -9.5 +2.00 x 174ª) was inserted uneventfully through a nasal corneal incision in the horizontal axis and then rotated 18º clockwise. One week later, an spherical ICL (VICM5, 13.2 mm, -9.5 D) was implanted on the fellow eye. One month later, uncorrected visual acuity was 1.0 on the right eye and 0.7 on the left eye, with refraction +1.25-1.25 x100º and +3.00-0.50 x 133º. Vault was considered correct for both eyes (220/587 microns). Patient satisfaction was very high with his final visual acuity.

Conclusions:

Ammetropia and irregular astigmatism as a result of corneal scarring after bacterial keratitis can be successfully corrected with the implantation of a toric implantable collamer lens in young non presbyopic adults.
