Compare potential visual acuity obtained before cataract surgery using Heine Lambda 100 retinometer with best corrected visual acuity 6 months postoperatively in nuclear lens opacification
Prospective study executed in the Ophthalmology Hospital Laser Vision in Santos of 121 eyes of 83 patients who underwent cataract surgery (phacoemulsification with intraocular lens implantation), from May to August, 2010. In the preoperative period, Heine retinometer test was performed under mydriasis and its results were compared to postoperative best corrected visual acuity 6 months after surgery and correlated with nuclear lens opacification, being considered a satisfactory result those who did not vary more than two lines in Snellen char
The satisfactory cases found in our study were 86.78%, with results of visual acuity with Heine retinometer equal to the postoperative visual acuity in 34.7% of the cases. Predominant nuclear opacity N1+ has a higher reliability than N2+ and N3+ (50%, 31.3% and 26.7%, respectively). Regarding all studied eyes, statistical significance was noted (p<0.0001).
In most cases Heine retinometer underestimated or maintained best corrected visual acuity 6 months postoperatively in patients who underwent cataract surgery with nuclear lens opacification.
