Purpose: The purpose of the study was to evaluate the visual functions after implantation of Acrysof monofocal intraocular lenses Alcon (SA60AT. MA50BM a SN60WF a SN6AT). Materials and methods: Four works are presented in the overview. The first work deals with the effect of eye length. corneal optic power and anterior chamber depth on the uncorrected near visual acuity (UNVA) after IOL implantation. The second work compares the effect of eye position (horizontal and vertical) on the final UNVA. The third work deals with the influence of the spherical lenses (SA and MA) and yellow aspherical lenses (SN) on UNVA. The later work examines the effect of pupil width on UNVA. Results: The first work showed the dependence of eye axial length (the largest in eyes bellow 22.5 mm. r = 0.36) on UNVA. 77.4 % of eyes with axial length below 22.5 mm had UNVA better than 0.5 and 70.49 % of all evaluated eyes had UNVA better than 0.5. Uncorrected far visual acuity (UDVA) better than 1.0 was in 97.54 % eyes in the whole group. In the second work we found a mean correlation in eyes shorter than 22.5 mm with UNVA in horizontal position (r = 0.39) and in the vertical position (r = 0.49). UNVA improved in these eyes in horizontal position from 0.53 to 0.58 in vertical position of the eye. In all eyes from the group UNVA changed from 0.51 to 0.56. The third work demonstrated the effect of sphericity and chromaticity on UNVA. Better than 0.5 in the group of eyes shorter than 22.5 mm in SA IOL in 67 % and in SN IOL in 60 %. In eyes with mean axial length was UNVA better than 0.5 in SA IOL in 86.5 %. in MA IOL in 81 % and in SN IOL in 75 %. In eyes longer than 23.5 mm was UNVA better than 0.5 in SA IOL in 100 % of eyes, in MA IOL in 60 % and in SN IOL in 33 % of eyes. In the fourth work the effect of pupil size was not demonstrated. Conclusion: The works showed excellent results of UNVA and UDVA after implantation of Acrysof monofocal lenses.

Czech Conclusions ensuing from the above overview The first study demonstrated a dependency of eye length (largest in eyes shorter than 22.5 mm, r = 0.36) on UNVA. 77.4 % of eyes with an axial length of less than 22.5 mm had UNVA better than 0.5, and 70.49 % of all evaluated eyes had UNVA better than 0.5. Uncorrected distance visual acuity (UDVA) was better than 1.0 in 97.54 % of eye throughout the entire cohort. In the second study we determined a medium correlation in eyes shorter than 22.5 mm with UNVA in horizontal position (r = 0.39), and in vertical position (r = 0.49). In these eyes UNVA improved from 0.53 in horizontal position to 0.58 in vertical position. The third study demonstrated the influence of sphericity and chromaticity on UNVA. UNVA better than 0.5 was recorded in the group of eyes shorter than 22.5 mm in 67 % of eyes with SA IOL, and in 60 % with SN. In medium- -length eyes UNVA better than 0.5 was recorded in 86.5 % eyes with SA IOL, 81% with MA and 75 % with SN. In eyes Zeng M, Liu Y, Liu X, Yuan Z, Luo L, Xia Y. el al.
