Visual Performance Of An Intraocular Lens With Asphericity Modulation Design With Combination Of 4Th And 6Th Order Of Spherical Aberrations With Opposite Sign

To analyze the visual performance after the implantation of an intraocular lens with an asphericity modulation design with the combination of 4th and 6th order of spherical aberration with opposite signs, in far, intermediate and near distance, as well as the efficacy and safety of this intraocular lens. 

Prospective consecutive case series in one single clinical site 

Prospective study in patients undergoing cataract surgery using phacoemulsification technique and LuxSmart intraocular lens implantation. At 6 months, uncorrected visual acuity at far distance (6 meters), corrected visual acuity at far distance (6 meters), visual acuity at intermediate distance (66 cm) and visual acuity at near distance (40 cm) were evaluated. The effectiveness and safety of the lens was analyzed. 

A sample of 51 eyes was obtained from 28 patients, of wich 17 were women and 11 men. The age range was from 44 to 89 years with a mean age of 64.40±9.77 years. The power range of the implanted lenses was between +0.00 and +31.00D with an average power of 12.73±9.79 diopters. 45 spherical lenses and 6 toric lenses were implanted. Preoperative visual acuity with correction was 0,72 ±0,23. Our results show best corrected visual acuity (BCVA) of 0,92±0,11 D, uncorrected visual acuity (UCVA) 0,75±0,23 D, uncorrected intermediate visual acuity of 0,80±0,11 D and uncorrected near visual acuity of 0,62±0,23 D. The efficacy index was 1,04, and the safety index 1,27

The results of this study show that the implantation of the LuxSmart lens is a safe and effective procedure, achieving good viual acuity in far, intermediate and near distances, providing greater independence from optical correction for functional vision. 

The results at extreme powers are just satisfactory as at intermediate powers.
