Objective

Best corrected visual acuity (BCVA), contrast sensitivity (CS) and functional visual complaints were examined in early cataract and after cataract surgery.

Methods

53 eyes with early cataract (BCVA 20/30: Snellen charts) were examined before and 12 months after cataract surgery. BCVA was tested using logMAR chart. CS was examined using computerized system of 8010 type in 6 spatial frequencies between 0.74 and 29.55 c/deg. Influence of glare was tested using BAT. Subjective visual functions were evaluted using a questionnaire (distance vision, near vision, mesopic vision and glare conditions). 22 subjects were examined as controls.

Results

BCVA was 0.52 (0.22-1.05) preoperatively and 0.83 (0.37-1.26) postoperatively. BCVA in patients in both terms was significantly lower compared to controls (p<0.001, p<0.05). CS in patients before surgery was significantly lower compared to controls (p<0.05 to p<0.001), in spite of significant improvement postoperatively (p<0.05 to p<0.001), first of all at intermediate and high frequencies. Glare had only nonsignificant influence. The questionnaire scores were correlated with visual performance in both terms.

Conclusions

The significant improvement of both BCVA and CS suggest that cataract surgery improve quality of life in early cataract. Questionnaire should be considered as adjuncts to BCVA and CS in evaluating of early cataract.
