AIM:To evaluate best corrected visual acuity(BCVA)and contrast sensitivity(CS)under mesopic condition with no glare in patients following implantation of three different kinds of aspheric acrylic monofocal intraocular lens(IOLs).<p>METHODS: Seventy-seven cases(90 eyes)of age-related cataract patients were selected, who were undergone phacoemulsification and intraocular lens(IOL)implantation in our hospital during December 2011 to November 2012. Preoperatively, the patients were randomly divided into three groups: 30 eyes(25 cases)were implanted with hydrophobic yellow-tinted acrylic(HOYA)IOLs in group 1; 30 eyes(28 cases)with hydrophilic acrylic IOLs(Rayner)in group 2; 30 eyes(24 cases)with hydrophilic acrylic surface heparin processing IOLs(XO)in group 3. All eyes were evaluated at 1 month and 3 months postoperatively. The BCVA and CS under mesopic condition without glare were measured and underwent statistical analysis.<p>RESULTS: There was neither statistically significant difference in the BCVA(<i>P</i>>0.05), nor statistically significant difference in CS results(after standardization of contrast sensitivity value: lgCS)(<i>P</i>>0.05)between groups under mesopic condition, but the lgCS of the HOYA group decreased slightly. <p>CONCLUSION: There were not marked differences of BCVA and CS between groups of patients at the follow-up intervals of 1 month and 3 months under mesopic condition. The blue-filter type artificial lens may protect the retina, thus, it is advisable to implant yellow-tinted filter blue artificial lens, especially for patients who are children or young persons.
