LONG-TERM RESULTS O OF EXTENDED DEPTH-OF-FOCUS INTRAOCULAR LENS IMPLANTATION IN GLAUCOMA PATIENTS

To evaluate the effectiveness of implantation of an intraocular lens with an extended depth of focus and a monofocal intraocular lens and compare the indicators of retinal photosensitivity in patients with glaucoma.

The patients were divided into two groups: in group I (69 patients (69 eyes)) an IOL with an extended depth of focus Lentis Comfort (Teleon Surgical BV,  Netherlands) was implanted in group II (60 patients (60 eyes)) a monofocal IOL RPR-2 (Reper-NN, Russia) was implanted.

After surgery, among all patients in both groups, there was an increase in the indicators of UCVA and BCVA (p<0.05). After 24 months, in group I, UCVA was 0.90±0.1, BCVA was 0.95±0.03, and in group II, UCVA was 0.91±0.16, BCVA was 0.94±0.03. In the group of patients where an IOL with an extended depth of focus was implanted, significant high visual acuity rates were observed at medium (0.51± 0.08) and short distances (0.45± 0.08) compared with monofocal IOL. These indicators remained stable throughout the observation period. In the long-term postoperative period in both groups, IOP remained within normal values (group I - 18.7± 2.5 mmHg, group II - 18.1±1.4 mmHg). According to the results of the evaluation of computer perimetry data in both groups, there was an improvement in retinal photosensitivity in all patients after surgery (in group I – MD -2.95±2.8 dB, PSD 3.47±0.79 dB, in group II - MD -2.8±1.9 dB, PSD 3.0±0.98 dB).

Implantation of an IOL with an extended depth of focus increases visual acuity, improves the quality of vision of patients with glaucoma and eliminates the need for additional eyeglass correction for the intermediate distance, without reducing the retinal photosensitivity according to computer perimetry.
