Purpose: To evaluate the visual outcomes of Technis Symfony(ZXR00) Extended Range of Vision IOL, +2.5D add AcrySof IQ ReSTOR(SV25T0) and +3.0D add AcrySof IQ ReSTOR(SN6AD1) MFIOL.
Method: 30 eyes of 30 patients were prospectively enrolled and stratified into three groups: Technis Symfony (Group-A, n=10), +2.5D add MFIOL (Group-B, n=10) and +3.0D add MFIOL (Group-C, n=10). Target refraction was emmetropia in all eyes. Subjective refraction, Defocus Curve (DC) and Contrast-Sensitivity (CS) were evaluated at 1st and 3rd month.
Result: At 3 months, the mean logMAR Uncorrected Distance Visual Acuity (UDVA) for group-A, B &C was 0.17; 0.13; 0.10 and mean spherical equivalent was 0.51; 0.35; 0.15 respectively.
Distance corrected intermediate (50 cm) visual acuity of N6 or better was achieved in 70% patients in group-A and 50% in both group-B&C. Distance corrected near (30 cm) visual acuity of N6 or better was achieved in 40% patients in group-A&B and in 100% patients of group-C.
At a defocus of -2.0 D, Visual acuity of 0.2 logMAR units or better was seen in 50 %, 40% and 80% patients in the three groups respectively whereas at a defocus of -2.5 D, it was 60% in group-C and 20% in both group-A&B. Group B had best photopic CS and group A best mesopic CS.
Conclusion: The new Technis Symfony IOL provides the best visual acuity at intermediate distances while best near visual acuity is provided by the + 3.0 add MFIOL(SN6AD1). Technis Symfony provides the best contrast sensitivity at night among the three lenses.
GLISTENINGS IN INTRAOCULAR LENSES IN AUSTRALIA AND NEW ZEALAND- A COLLABORATIVE SURGICAL QUALITY AUDIT OVER THE 24 MONTH PERIOD UP TO FEBRUARY 2017. FINDINGS OF THIS AUDIT OF LENSES IMPLANTED BETWEEN 1995 AND 2016, HIGHLIGHT THE ONGOING PRESENCE AND SEVERITY OF VACUOLES EVEN IN THE MOST RECENTLY IMPLANTED LENSES.
