Abstract
Purpose::
Authors present clinical effects of AcrySof Restor IOL, Technis ZM900 and ReZoom IOL implantation in cataract surgery.
Methods::
In group 1, test group, AcrySof Restor IOLs were bilaterally implanted to 5 patients (N=10 eyes), axial length was measured by A scan ultrasonography and they were over 70 years old. Also we targeted emmetropy. In group 2, cataract group, AcrySof Restor IOLs were bilaterally implanted in 130 eyes, Technis ZM900 in 20 eyes and ReZoom IOL in 30 eyes. We used optical biometry, IOL Master. Patients were between 60 and 70 years old. We targeted slightly hyperopic (+0.25 to +0.50). We measured postoperative UCVA, patient's satisfaction, spectacle dependence and visual disturbances.
Results::
In group 1 distance UCVA was poor (60% patients 0.1; 20% patients 0.2). They needed correction by -1D to -4D. In group 2, distance UCVA was very good (71.4% patients 1.0; 14.3% patients 0.9). Near UCVA was good in both groups (66.6% patients J1). High patient's satisfaction was noticed (91.0 % patients would implant AcrySof Restor IOL again). In group 1, patients had to wear glasses for distance vision all time, while in group 2 more than 70% of patients never wear glasses for distance. Near spectacle dependence was low in both groups. Serious visual disturbances were not reported.
Conclusions::
All 3 IOLs provide good near and distance vision with important difference in UCVA between Restor and Technics IOL. Patients with ReZoom lenses have better intermediate vision but more night-time driving difficulties then Restor and Technics patients. Patients with ReZoom lenses have more difficulties to read in scotopic condition.
