[Iris-claw phakic intraocular lens for high myopia correction. Visual and refractive results].
OBJECTIVE
To determine predictability, efficacy, complications and patient's satisfaction to phakic intraocular lens (Artisan) in highly myopic patients.


METHODS
Retrospective study of 65 eyes (36 patients), with preoperative spherical equivalent (SE) between -9,75 and -25,0 diopters (D) operated on by a single surgeon (JAD) between January 1999 and August 2001. Uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), refraction, postoperative complications, and patient's subjective response were evaluated.


RESULTS
UCVA evaluated 3 months postoperatively was 0.47 and BSCVA was 0.62. An average gain of 2.3 lines was observed with respect to the preoperative BSCVA. Refraction between +/-0.50 D from emmetropia ocurred in 49.23% of the eyes, and between +/- 1.0 D in 78.46% of the eyes. The difference between intended SE (preoperative SE minus IOL diopter) and achieved postoperative SE, showed a 0.55 D mean undercorrection. An intraocular pressure (IOP) over 30 mmHg was seen in 10% of the eyes in the immediate postoperative period. Night halos/glare perception was <<mild>> in 20% of the eyes, and in 90.77% of the cases the patient showed satisfaction with the results of the procedure.


CONCLUSIONS
Artisan iris-claw phakic lens implantation in highly myopic eyes is a safe procedure that increases BSCVA. It was observed a tendency towards undercorrection in the postoperative refractive outcome.
