Treatment of keratoconus by toric foldable intraocular lenses.
OBJECTIVE
To report on the correction of marked regular corneal astigmatism due to keratoconus by toric intraocular lenses (IOL).


METHODS
University eye hospital.


METHODS
A 66-year-old woman presented with cataract and unilateral keratoconus (keratometric readings: 50.2/41.3 diopters [D]). She underwent routine cataract surgery with implantation of a foldable posterior chamber toric IOL (refractive power: +10.0 D sphere/+12.0 D cylinder). A 68-year-old surgically aphakic woman presented with peripheral accentuated keratoconus with regular and stable corneal astigmatism (keratometric readings: 39.75/61.5 D). She underwent secondary implantation of a foldable toric IOL (refractive power: -9.0 D sphere/+30.0 D cylinder) into the ciliary sulcus.


RESULTS
After a follow-up period of 4 months, visual acuity increased to 0.70 with a correction of +0.75 sphere -2.5 cylinder/84 degrees in Patient 1; after a follow-up period of 6 months, visual acuity increased to 0.60 with a correction of +1.0 -2.0/90 degrees in Patient 2.


CONCLUSIONS
Foldable toric silicone IOL may be a surgical option in the management of regular marked corneal astigmatism caused by keratoconus.
