Abstract Details

Purpose:

To demonstrate experiences and results of toric intraocular lens (IOL) implantation after penetrating keratoplasty in patients with astigmatism and cataract.

Setting:

Department of Ophthalmology, University of Debrecen, Debrecen, Hungary

Methods:

Twelve eyes of 12 patients (mean age 42�Â�±12.6) with more than 3.5 diopters (D) astigmatism following penetrating keratoplasty were included in this retrospective study. Indications for corneal transplantation were keratoconus n=8, metaherpetic keratitis n=2, corneal dystrophy n=2. Suture removal was performed after 6 months, phacoemulsification with toric IOL implantation (cylindrical diopter range 1.5D-12D) was done after 37 months in average after keratoplasty. Visual acuity, topographic keratometry measurements and detailed ophthalmic examinations were performed in every patient. The mean follow-up was 9 months.

Results:

Corrected distant visual acuity (CDVA) improved continuously from 0.19 to 0.84 (p<0.0001) at the end of the follow-up period. Seven patients (58%) disclosed 0.9-1.0 distant visual acuity without correction. Spherical correction was necessary in 4 cases (33%) with the absolute mean of 1.75D. Average manifest cylindrical refraction reduced from 3.89D to 1.81D (p=0.02). Topographic astigmatism was 7.0D before surgery and changed to 5.6D (p=0.3). One patient complained about glare vision. All transplants remained clear and transparent.

Conclusions:

Toric IOL implantation is one of the effective, predictable, and safe procedure to simultaneously solve astigmatism and cataract in patients after corneal transplantation.
