RESUMO
BACKGROUND: We evaluate the Visian Implantable Collamer Lens (Staar, Monrovia, CA, USA) phakic intraocular lens for treating post-keratoplasty anisometropia. METHODS: Case series of three eyes (2 phakic and 1 pseudophakic). RESULTS: The mean age was 47.3 years (range 30-73 years), with a minimum of 3-month follow up. The mean preoperative spherical equivalent was -8.75 ± 5.17 D (-4.00 to -14.25 D) improving to -0.29 ± 1.21 D postoperatively (range 0.75 to -1.625 D). Mean logMAR uncorrected visual acuity improved from 1.66 ± 0.60 (6/240) preoperatively to 0.41 ± 0.52 (6/15(2) ). Mean logMAR best spectacle-corrected visual acuity improved from 0.32 ± 0.15 (6/12) preoperatively to 0.10 ± 0.11 (6/7.5). Anisometropia improved from a difference of 6.37 ± 2.59 D preoperatively to 2.09 ± 1.37 D postoperatively, and there were no complications. CONCLUSION: Our technique for this clinical indication shows that the Visian Implantable Collamer Lens is a safe and effective alternative for treating post-keratoplasty anisometropia.

We report a case of sterile keratitis after Ferrara intracorneal ring (Ferrara Ophthalmics) implantation into the right cornea of a keratoconus patient who also suffered from atopic blepharoconjunctivitis. The keratitis resolved within a few days after removal of the Ferrara rings. Ocular atopy with sterile keratitis should be considered in the differential diagnosis of keratitis after the insertion of intracorneal ring segments, which can be easily treated by ring removal.
