To evaluate if implanting, after cataract surgery, apodized refractive IOLs it is possible restore distance and near sight in patients with retinitis pigmentosaavoiding further complications.
Two groups of 6 RP patients selected for good macular conditions were randomized for bilateral cataract surgery, in the first one was implanted Acrisof SNA60WF IOL (AS) while in the second a Restor (RS) apodized IOL. The surgical procedure was the same for both group and in each of them 90 days after the surgery were measured corrected and uncorrected far and near visual acuity, and computerized visual field (HFA 10-2) registering any coplication following the surgery. Target VA was 25/20 for distance and 10 pts for near.
In both groups was reached by all patients target far visual acuity (20/25) 4 patients (66,66%) uncorrected in AS group and 6 (100%) in RS group, all patients reached near target visual acuity (10 pts) in AS group in 3 (50%) patients with an addiction of +3D and in 3 (50%) patients with an addiction of +4D; in the RS group 2 patients needed +1 D. Visual Field retinal sensitivity starting from 16.32 dB +/- 4.33 improved after cataract surgery to 21.71 dB +/- 5.19 in AS group and from 15.06 dB +/- 4.12 improved after cataract surgery to 21.11 dB +/- 4.89 in RS group this value was not significative. In AS operated patients we registered during the follow-up 2 eyes (16,66%) with macular edema and 11 eyes (84,34%) with capsular opacities needing Yag Laser capsulotomy. In RS group we had no macular edema and performed capsulotomy in all patients (100%).
Our data indicates that Restor IOL allows a better visual acuity either for distance than for near vision, moreover there is a statistically significative difference in retinal complications after cataract surgery infact none of the patients with Restor had macular edema, thus depending from light amount divided in two focal points, mainly for infinity but in part for near vision. In that case there is an higher and safer light threshold on retina and thus may cause a reduction in Cystoid macular edema occurrence. Moreover RP patients are younger than senile cataract and reudcing the need of near glasses may be useful to improve their quality of life.
