Abstract Details


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.


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


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 ).


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.


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.
