Abstract Details

Purpose:

Last years the number of patients with combination of induced hyperopia and presbyopia considerably increased. This is associated with previously performed correction of different myopia degrees by radial keratotomy (RK). These patients prefer to refuse from glasses and are looking for alternative methods of vision correction. The purpose of our work was to evaluate the results, safety and effectiveness of Supracor method, (according to near and far vision acuity) in cases of previously performed RK with lately induced hyperopia and combined with presbyopia.

Setting:

Eye Center East Sight recovery

Methods:

Supracor was performed in 5 patients (10 eyes) 46 to 56 years of age. All patients in young years had myopia corrected by RK and later by the moment of presbyopia formation they had induced hyperopia from +1.25 to +3.25 sphere and astigmatism from +0.5 to +2.25. Before operation uncorrected distance vision acuity (UDVA) was 0.3 ± 0.25; uncorrected near vision acuity (UNVA) was 0.08± 0.05. All patients used glasses for near vision and 3 from 5 patients constantly used glasses for distance vision. The observation period was 1 year.

Results:

In 1 month after the surgery UDVA was 0.85± 0.13; in 6 months - 0.9± 0.08; in 1 year 0.89± 0.16. UNVA was 0.7± 0.18; 0.7± 0.25; 0.68± 0.1 correspondingly 1 month, 6 months and 1 year after the operation. All patients were satisfied with the results and absolutely refused from glasses.

Conclusions:

Supracor appeared to be a successful method of induced hyperopia correction with its combination with presbyopia after previously performed RK. All patients are satisfied with near and distance vision results. The results were stable from 1 month after the procedure. There were no patients using glasses in postop period. There were no complications either during or after operation. Only in 1 case vision acuity decreased in 1 line according to cataract formation. Later phacoemulsification with monofocal IOL implantation was performed in this case. FINANCIAL INTEREST: NONE
