Comparison Of Visual Outcomes And Contrast Sensitivity Of Monofocal Lens With Higher-Order Aspheric Optic And Standard Aspheric Monofocal Lens – 12 Months Overview Results.

To compare the 12-month outcomes of visual performance and patient satisfaction between a higher order aspheric monofocal intraocular lens (IOL) and monofocal lens.

Faculty hospital Královské Vinohrady, Prague

Patients who underwent bilateral cataract surgery with implantation of an enhanced monofocal lens in one eye and a monofocal lens in the fellow eye were included. Patients were evaluated at 3, 6, and 12 months after surgery. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity (UIVA), distance corrected visual acuity (DCIVA), uncorrected near visual acuity (UNVA), and distance corrected near visual acuity (DCNVA) were compared at 12 months postoperatively. Contrast sensitivity, defocus curves, and reading text size were evaluated. Patient satisfaction was assessed with a questionnaire at the 6 month follow-up.

Twenty-two patients were enrolled (22 eyes per group). UDVA and CDVA were similar between the two groups. Monocular UIVA and DCIVA were significantly better in the enhanced IOL group (P=.01), whereas UNVA and DCNVA did not differ significantly between the groups. The size of the reading text was significantly better in the enhanced IOL group for both tested distances (P=0.04 and P=0.02). The contrast sensitivity results were similar between the two groups. Patients reported high overall satisfaction, with 62% of patients using glasses for reading in everyday life. 

The eyes of patients receiving enhanced monofocal IOL had significantly better visual acuity for intermediate distances with the same contrast sensitivity as the monofocal lens.
