Abstract Details

Purpose:

The aim of the study was to evaluate clinical outcome, rotational and refractive stability after the implantation of monofocal toric IOL: Bi-Flex 677TY (Medicontur).

Setting:

Department of Ophthalmology, Institute of Aviation Medicine, Prague, Czech republic.

Methods:

In this prospective, interventional case series study 20 toric Bi-Flex 677TY (Medicontur) were implanted in 13 consecutive patients with topographic corneal astigmatism between 1.0 and 4.7D. Clinical outcomes were assessed 1 and 7 days, 1 and 3 months postoperative. all patients underwent biomicroscopic examination, included measurement of intraocular pressure (IOP) with Goldmann tonometer. Best distance-corrected (BCDVA) and uncorrected (UCDVA) visual acuity were tested at distance (4m) using ETDRS charts. For each visit photo-documentation in retro-illumination was performed to evaluate torus position and potential IOL rotation.

Results:

The improvement of the mean spherical equivalent was from 5.75D to 0.5D and improvement of the mean cylinder was from 3.2D to 0.25D. The mean monocular UCDVA, was 0.92 in decimal scale. All patients achieved spherical refractive precision within plus/minus 0.5D. Intraoperative to 3 month postoperative comparison of IOL axis alignment showed low levels of rotation. Mean rotation was 1.94±1.84°. Majority of rotation occurred first 24 hours after surgery.

Conclusions:

The evaluated toric IOL provides safe and effective correction of pre-existing regular corneal astigmatism in patients after cataract surgery. The lens provides very good level of refractive precision and rotational stability.
