Abstract Details

Purpose:

Evaluation of functional vision, objective task assessment and patient reported spectacle use in patients undergoing lens replacement surgery using Monofocal IOLs with enlarged depth of focus.

Setting:

Private Practice and Research Centre

Methods:

A single surgeon cohort of 30 consecutive patients undergoing lens replacement surgery using monofocal IOLs with enlarged depth of focus had functional vision measurements in the form of binocular uncorrected and distance corrected, distance, intermediate, near visual acuity measurements in standardised photopic conditions and near vision in standardised mesopic conditions. Intermediate and near vision task performance was tested objectively and a questionnaire was administered to capture patient perception of their spectacle free vision for distance activities in good and poor light, intermediate activities in good light and near activities in good and poor light.

Results:

Binocular uncorrected visual acuity was better than or equal to 6/9 for distance and intermed in more than 92% of patients; while 75% of patients achieved 6/9 or better for near photopic visual acuity. only 40% of patients achieved 6/9 or better mesopic near visual acuity. More than 90 % of patients were satisfied with their spectacle free distance vision in both good and poor light conditions and intermediate vision. 2 out of 3 patients were using specs for near reading tasks sometimes and were able to function most of the times without spectacles. 95% of patients were able to carryout intermediate vision tasks and 66% were able to carry out most near tasks in photopic conditions.

Conclusions:

The use of monofocal IOLs with enlarged depth of focus provides excellent quality of vision and reasonable range of spectacle free vision. The vast majority of patients were only using spectacles for fine near vision tasks.
