Contrast Sensitivity Test In Hydrophilic Versus Hydrophobic Intra

Abstract

Abstract: : Purpose:: To compare the contrast sensitivity test in hydrophilic versus hydrophobic intraocular lens(IOL). Methods:We compared visual quality using a contrast sensitivity test (Vistech Consultants Inc) in patients who underwent cataract extraction by phacoemulsification (alcon legacy) and intraocular lens implantation.(using acrylic and hydroxipolimetilmetacrylate)with the following characteristics: a follow up of at least six weeks, with a visual acuity of 20/30 or better,with no surgical complications, with a pupil diameter of 2-3 mm and low refractive result (low sphere value –2.00 or +2.00 and a cylinder less than –2.00). Results:Hydrophilic IOL presented better contrast sensitivity in low and medium frequencies at 3 mts.Hydrophobic ones obtained a result inside the median averge. At 40 cm the results for both lens were inside the average with the same results. Conclusion:Even the hydrophilic lens provide better results than the hydrophobic in median and low frequencies , this is not significant to establish a real difference between both lens . The new materials of intraocular lens gives the surgeon a wide variability of options to search for visual excellence.
