Abstract Details

Purpose:

To evaluate refractive outcomes, rotational stability and safety of lens exchange with customized AT TORBI 709M/MP (Carl Zeiss) intraocular lens (IOL) in eyes previously underwent radial keratotomy (RK), thermokeratoplasty (TKP) and penetrating keratoplasty (PKP) in the eye with induced astigmatism.

Setting:

“Blue Eye” Centro di Chirurgia Oculare, Milano, Italy, “International Center for Ophthalmology”, Moscow, Russia

Methods:

This retrospective, case series study enrolled 22 eyes of 16 patients (mean age: 52 ± 6,2 years, range 33-76 years, with astigmatism induced by previous corneal surgery: RK (11 eyes), TKP (4 eyes), PKP (7 eyes). Preoperatively induced astigmatism range 3,5 to 18.0 D. Mean uncorrected distance visual acuity (UDVA) was 0.8 LogMAR and corrected distance visual acuity (CDVA) was 0.5 LogMAR were calculated. Each IOL power was calculated and manufactured by Carl Zeiss Meditec based on individual patient`s data. Postoperatively manifest refraction, UDVA, CDVA, IOL rotation complications and adverse events were assessed at 6 to 24 months follow-up period.

Results:

Mean postoperative follow-up was 24 ± 5 months. At last postoperative follow-up mean sphere was +1,75 ± 0, 25D (range: +0,75 +4,0 D), cylinder was 5 ± 0,5D (range: -1,0; -9,0D). Mean UDVA was 0.3 LogMAR and CDVA was 0.1 LogMAR . IOL rotation was not seen in all cases. No intra- or postoperative surgical complications were observed. 2 patients had high IOP at 1 month follow-up which was corrected with drops. 2 eyes of 2 patient required of YAG laser capsulotomy because of posterior capsule opacification at 6 months after surgery. No other adverse events were noticed.

Conclusions:

Lens Exchange for customized toric IOL is safe, predictable and stable solution for correction of high level of induced corneal astigmatism in eyes that underwent corneal transplantation and corneal refractive surgery in the past and in eyes with regular astigmatism.
