Abstract Details

Purpose:

To report the results of toric intraocular lens (IOL) implantation in two cataract patients with irregular corneal astigmatism due to keratoconus and very steep cornea.

Setting:

Department of Ophthalmology, Haseki Training and Research Hospital, Istanbul, Turkey

Methods:

Case 1 was a 72-year-old man with cataract and atypical superior-nasal keratoconus in the left eye. He underwent phacoemulsification with toric IOL ( Acriva T UDM 611; cylinder power: 7.0 D, VSY Biotecnology, Turkey). Case 2 was a 77-year-old woman with bilateral cataract and very steep cornea ( SimKmin and SimKmax values were 46.7D- 52.2 D and 47.5 D - 52.3 D in the right and left eyes, respectively). Bilateral phacoemulsification was performed with toric IOL implantation ( Acrysof SN6AT8 and Acrysof SN6AT7 , Alcon Laboratories Inc, in the right and left eye, respectively ).

Results:

The follow-up periods were 10 and 31 months in the case 1 and case 2, respectively. In case 1, uncorrected distance visual acuity(UDVA) increased from 20/160 to 20/50. The refractive cylinder decreased from -8.00 to -1.75, which is a reduction of 78%. In case 2, UDVA increased from 20/100 to 20/40 in the right eye and from 20/100 to 20/32 in the lefte eye. Refractive astigmatism decreased from -4.25 to -1.0 in the right eye and from -4.5 to -0.75 in the left eye. No IOL rotation or other complications were observed.

Conclusions:

Cataract surgery with toric IOL implantation seems to be a safe and effective option in correcting mild irregular astigmatism and improving visual function in selected cases with keratoconus and steep cornea.
