- W2317150550 abstract "Purpose To evaluate the correlation between the subjective visual parameters and the objective optical quality parameters, before and after the laser YAG-Neodymium treatment in patients with posterior capsular opacification (PCO).Methods Prospective study in 30 eyes (30 patients) referred to our service for capsulotomy, without remarkable ocular story except a non complicated phacoemulsification with intraocular implant. We quantify visual acuity (VA), contrast sensitivity (CS) and objective parameters of vision quality measured with a double pass system (Optical Quality Analysis System,Results 78.5 ± 5.4 years was the average age of our patients, the 65.4% were women. Visual acuity values, intraocular scattering index (OSI) and Strehl ratio before the treatment were respectively: 0.4 ± 0.2; 5.84 ± 3.43; 8.89 ± 7.32; 0.06 ± 0.04. We found a moderate, inverse and statistically significant correlation between OSI values and VA before the treatment: -0.564 (p value= 0.003). And also a strong and inverse correlation between OSI values and CS values at 1.5, 3, 6 y 12 cycles per degree (cpd): -0.665 (p value < 0.001); -0.733 (p value < 0.001); -0.725 (p value < 0.001) y -0.785 (p value < 0.001) respectively. After capsulotomy, all the parameters, subjective and objective, improved significantly, except the CS at 18 cpd. However, we did not find any significant correlation between OSI and the subjective parameters after treatment.Conclusion Tthe determination of OSI values is a useful tool to establish the indication of treatment in patients with suspicion of clinical PCO. Once eliminated the main limiting factor of visual quality, PCO, the absence of correlation indicates the influence of other limiting factors in visual quality." @default.
