Abstract Details

Purpose:

To present the refractive and clinical outcomes in a group of patients operated for cataract with  implantation of a Technis toric aspheric intraocular lens (IOL). The rotational stability and the refractive predictability of the lens were also followed with an additional comparison of the rotational stability between medium-power, low-power and high-power IOLs, respectively, between emmetropic, big myopic eyes and relatively small hyperopic eyes.

Setting:

Oculus Eye Clinic – Bucharest, Romania

Methods:

This retrospective study consists of 84 eyes with cataract and corneal astigmatism between 0.5 to 6 D. After phacoemulsification, a Tecnis  toric intraocular lens was implanted in the capsular bag; the toric alignment during surgery was done using Verion image guided system, following the indications provided by the Online Technis Toric Calculator. The toric IOLs implanted varied between ZCT150 and ZCT700 and their spherical diopters between 5 D and 28 D.  The postoperative distance UCVA, BCVA, objective and subjective residual astigmatism and spherical equivalent (SE), spectacle independence and IOL axis alignment were measured at 1 and over 6 months postoperative.

Results:

The study includes 84 eyes (62 patients). The mean SE deviation from target refraction at one month was 0.53D and at 6 months 0.21D. At one month, 83% of eyes achieved postoperative UCVA of 0.6 or better and 75% of 0.7 or better. The BCVA was 0.9 or better in 70% of eyes. The postoperative subjective refractive  cylinder was 0.5 D or less in 78% of eyes at one month and in 87,5% of the eyes at 6 month. IOL axis rotation was 5° or less in all eyes with 80% of the eyes within 2 degrees of rotation.

Conclusions:

Our study results show that the implantation of the Technis toric IOL is a safe and effective procedure to compensate for corneal astigmatism in cataract patients. The Technis toric platform showed a good refractive predictability with excellent clinical results provinding patients with high postoperative satisfaction due to an increased rate of spectacle independance, with no difference between myopic, emmetropic or hyperopic eyes.
