Abstract

PLASENCIA BLANCO, Abel et al. Results of the optimal visual quality in patients operated on from cataract at “Ramon Pando Ferrer” Cuban Institute of Ophthalmology in 2009. Rev Cubana Oftalmol [online]. 2011, vol.24, n.2, pp.299-311. ISSN 0864-2176.

Objective: To assess the results of good visual quality in patients operated on from cataract, taking ocular aberration as a decisive factor. Methods: A prospective, observational, and longitudinal study of aberrometric modifications (measured by the OPD Scan II Nidek) in the cataract surgeries performed from January to July 2009 at the Ocular Microsurgery Department in “Ramón Pando Ferrer" Cuban Institute of Ophthalmology. Of the universe of 353 patients, 300 eyes operated from cataract from 220 selected patients were used. All the cases were surgically treated by the same surgeon who used the same technique called phacoemulsification. The variables under study were best corrected visual acuity pre and postoperative, Function of modular transfer, Strehl’s, wave front error, sensitivity on contrast test, and internal and total corneal aberrations and before and after surgery. The results were shown in charts with absolute and relative frequencies based on reliable statistical methods. Results: The best corrected visual acuity improved 4,5 lines in the Snellen’s chart. The values of function of modular transfer and the Strehl’ index increased but the wave front diminished. The internal and the total aberrations increased but the corneal aberrations did not change significantly. Conclusions: The patients included in this study obtained a quality visual in agreement physics to the opposing biological results, element that endorses the necessity to make this mensurations systematically so that the biggest visual perfection is always achieved that contributes the patient an useful social life.
