Abstract Details

Purpose:

The purpose of the study was to compare and report the quality of life and patient satisfaction levels between 2 groups of patients. First group with customized monovision (CM) pseudophakia( -1.5D myopia for mild monovision in patients requiring more intermediate vision , -2.5D myopia for moderate monovision in patients requiring more near work) and second group with bilateral aspheric diffractive multifocal intraocular lenses(MFIOL).

Setting:

Tertiary Eye Care and Teaching Hospital , India

Methods:

35 patients with CM and 24 with bilateral MFIOLs, were evaluated 6 weeks after bilateral uncomplicated cataract surgery (final visit). Unaided visual acuity for near and distance, final refraction for monovision group and residual refractive error for MFIOL group was measured. The patients were also given a questionnaire, VF-14- QOL, at the same visit. Patients were asked to rate 14 daily activities depending upon degree of difficulty they faced while doing that particular activity. Answers were rated from 0 for not being able to do a task, to 100 if they could do the task without any difficulty. Average scores for all 14 questions were calculated for both groups and analyzed.

Results:

Mean age of patients was 60.28+/-9.79 yrs and 61.16+/-10.35 yrs for CM and MFIOL groups respectively. The mean myopia in monovision eye in CM group was -1.97 D. The mean distance Spherical Equivalents in MFIOL were -0.17 D in the right and 0.075 D left eyes, respectively. When asked about difficulty level in reading small print, news paper and large prints CM scored 86.02, 92.85, 97.85 and the MFIOL patients scored 84.37, 90.62, 98.95. About being able to recognize faces, difficulty in climbing stairs and seeing traffic signs CM scored 98.57, 97.85, 91.91 and MFIOL scored 98.95, 100, 95.83. About difficulty in writing checks and doing fine handiwork CM scored 87.5, 97.22, MFIOL scored 93.75, 95.65. On difficulty while playing indoor and outdoor games CM scored 95.83, 100 and MFIOL scored 100, 100. When asked about difficulty while watching television and cooking CM scored 96.05, 93.57 and MFIOL scored 94.11, 95.83. On difficulty while driving during the day and night CM scored 97.22, 94.44 and MFIOL 96.87, 68.75. Total score was 94.29 for CM and 94.58 for MFIOL. Apart from driving in the night (p= 0.045) there was no significant difference in any other groups.

Conclusions:

Quality of life and satisfaction levels in patients with customized monovision pseudophakia and bilateral multifocal IOLs are comparable in the Indian scenario. Moreover the fact that majority of patients in India don’t have adequate financial resources, customized monovision which is tailored to the patients visual needs may be a cheaper and effective alternative to multifocal lenses.
