Purpose:
To examine a single-optic accommodating intraocular lens (IOL) visual performance by correlating IOL implanted eyes' defocus curve with the intraocular aberrometric profile and the impact on the quality of life (QOL)
Setting:
Department of Ophthalmology (Oftalmar), Medimar International Hospital, Alicante, Spain
Methods:
Prospective consecutive case series study including a total of 25 eyes of 14 patients with ages ranging between 52 and 79 years old. All cases underwent cataract surgery with implantation of the single-optic accommodating IOL Crystalens HD (Bausch & Lomb). Distance and near visual acuity outcomes, intraocular aberrations, the defocus curve and QOL (NEI VFQ-25) were evaluated 3 months after surgery.
Results:
A significant improvement in distance visual acuity was found postoperatively (p=0.02). Mean postoperative LogMAR uncorrected near visual acuity was 0.44±0.23 (20/30). 60 % of eyes had a postoperative addition between 0 and 1.5 D. The defocus curve showed an area of maximum visual acuity for the levels of defocus corresponding to distance and intermediate vision (-1 to +0.5 D). Postoperative intermediate visual acuity correlated significantly some QOL indices and one power vector component of manifest cylinder. Postoperative distance-corrected near visual acuity correlated significantly with age (r=0.65, p<0.01).
Conclusions:
This accommodating IOL is able to restore the distance visual function as well as to provide an improvement in intermediate and near vision with a significant impact on patientÂ’s QOL. Age and astigmatism are limiting factors for the outcomes with this type of accommodating IOL. FINANCIAL DISCLOSURE?: No
