Abstract Details


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.


Oftalvist Group, Juan Bravo 1, Madrid, Spain.


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.


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.


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.
