Purpose:
To report the long-term performance of the Diffractiva-aA intraocular lens after cataract surgery. This new one-piece hydrophilic acrylic MIOL is commercially available in Europe since September 2010.
Setting:
Four university clinics or private ophthalmic surgical centers in Europe
Methods:
This prospective multicentre study comprised 30 patients (60 eyes) with bilateral cataract and eligible for MIOL implantation. Examinations including refraction, monocular and binocular visual acuity for distance, intermediate (1 m) and near (40 cm), contrast sensitivity, defocus curve, patient satisfaction (quality-of-life questionnaire) and incidence of PCO were scheduled at 1-month, 6-month and 1 year postoperatively. Near and intermediate VA were tested with the logarithmic visual acuity chart 2000 “New ETDRS” (Precision Vision) and contrast sensitivity with the Optec® 6500 Vision Tester. RESULTS At the time of submission, data of 17 patients (34 eyes) were available for the 6-month follow-up. Mean SE was 0.12±0.31 D; uncorrected monocular distance (UDVA), near (UNVA) and intermediate (UIVA) visual acuity was 0.05±0.08 logMAR (decimal 0.91±0.15), 0.07±0.09 logMAR (decimal 0.86±0.17) and 0.16±0.12 logMAR (decimal 0.72 ± 0.19), respectively. Binocular UDVA, UNVA and UIVA was 0.01±0.06 logMAR (1.00±0.13), 0.03 ± 0.05 logMAR (0.93±0.10) and 0.10±0.11 logMAR (0.82±0.18), respectively. Contrast sensitivity was within the normal range under photopic conditions. Under mesopic conditions, a reduction in contrast sensitivity was noted only at 6 and 12 cpd. The quality-of-life questionnaire revealed that 93.3% of patients were not using spectacles at any time and 6.7% reported to wear glasses “very rarely”. The majority of patients did not experience night visual symptom such as glare, halo, and starburst. Overall, all patients were “very satisfied” (87%) or “satisfied” (13%) with the procedure. No eyes required neodymium:YAG capsulotomy.
Conclusions:
The new Diffractiva-aA MIOL provides good far, near and intermediate vision. The level of patient satisfaction was high due to high rate of spectacle independence and minimal photic phenomena at night.
