to determine the functional consequences and complications of Nd:YAG capsulotomy
A prospective study was reported on 32 patients (37 eyes)having a Nd:YAG capsulotomy. As excluded criteria were associated pathologies. All cases were operated by the same surgeon, the procedure was phacoemulsification and the IOL an hydrophobic acrylic. The mean diameter of the capsulotomy was of 2.5mm. Follow-up time was six months. Visual acuity, IOP, OCT, IOL,and contrast sensitivity were evaluated, with a questionnaire of quality of vision. Statistical analysis was done with the SSPS 13.0.
Mean age was 74 y. Average apparition of posterior capsular opacification was of 3+/-1.6 y. After laser treatment,VA did not change, like the contrast sensitivity at different controls. No significative difference was observed on contrast sensitivity between eye having capsulotmy and the other without PCO not, like on the values of IOP pre and post laser.No other complications were observed, as retinal detachment, macular edema.
Laser yag capsulotomy improve the visual acuity , and quality of vision, only when PCO was present and must be treated.Even if complications are rare, the systematic opening of posterior capsules does not present any visual benefit.
