Influence of age, corneal astigmatism and some characteristics of intraocular lens on glare in pseudophakic persons
Background/Aim. Although an extraordinary visual acuity is achieved following the extracapsular cataract extraction with the implantation of intraocular lens, all the problems of vision are not solved in so doing and many of them should be considered.

| description | Background/Aim. Although an extraordinary visual acuity is achieved following the extracapsular cataract extraction with the implantation of intraocular lens, all the problems of vision are not solved in so doing and many of them should be considered. The aim of this study was to establish the influence of age, dioptric power of intraocular lens, corneal astigmatism and optic diameter of intraocular lens on glare in pseudophakic subjects. Methods. We examined 152 patients who underwent final correction at least two weeks after the suture removing what was performed if the astigmatism more than 2.0 D was measured by the use of a Javal keratometer. Examination was performed by a Rodenstock Adaptometer Nyctomat. According to the recommendation of the manufacturer, healthy persons should notice 50% of contrast under the constant glare and in the given time. Statistical data processing was performed by χ2 test. Results. In the group of patients with the findings lower than normal at constant glare there were 112 of eyes (73.68%) as follows: 22 eyes (14.47%) at the age from 50-55 years; 15 eyes (9.87%) were at the age from 56-60 years; 18 eyes (11.84%) were at the age from 61-65 years, and 57 eyes (37.50%) were at the age from 66-70 years. Dioptric power of lenses up to 20.0 D had 37 eyes (24.3%), from 20.5-22.0 D 85 eyes (56.9%) and more than 22.5 D, 27 eyes (17.8%). Regarding the results of discomfort caused by glare and corneal astigmatism, measured by a Javal keratometer, in the observed group normal results were found in 112 eyes (73.68%), and out of that number 95 (62.50%) were with corneal astigmatism less than 20.0 D, and 17 (11.18%) had astigmatism of 20.0 D and more. Out of 112 eyes there were 58 of them (38.16%) with findings lower than normal in relation to the constant glare and with the lens diameter of 5.5 mm, 48 (31.58%) with the lens diameter of 6.0mm, and 6 of them (3.95%) with lens diameter of 6.5mm. Conclusion. The study determined a significant statistical correlation between the dioptric power of lenses and the glare. The obtained results did not find out a significant increase in glare in relation to the age of subjects, optic diameter and corneal astigmatism. |
