Optical Performance And Visual Outcome Of Iol With Controlled Positive Spherical Aberration.

To evaluate optical performance and near reading speed test, in patients having surgery with implants of IOL’s design with a controlled Spherical aberration (RayOne EMV)

Single Site study

This is a prospective study of 110 eyes (55 patients) undergoing uncomplicated cataract surgery with controlled spherical aberration IOL implantation (RayOne EMV).

Patient were targeted for Emmetropia on dominant eye and a light micro-monovision on non-dominant eye (0.00D to -0.50D)

The near reading speed test (40 cm) was conducted in monocular and binocular vision, where the acuity determination was the size of the last completely read sentence.

Preliminary test analysis: Tear film, Aberrometry, Lens Tilting, Pupillometry, in addition to standard test.

The result of study shows a stable and excellent result in terms of target refractive outcomes SEQ.

Mean age was 64 (from 46 to 83).

IOL Power between +12.00D to +27.00D.

Post-op refraction: UDVA was 0,1 logMAR in all cases, UNVA monocular 0.5 logRAD, UNVA binocular 0.4 logRAD

Near reading Speed test (40 cm): Monocular 80 w.p.m. at 0.5 logRAD at 40cm, Binocular 80 w.p.m. at 0,4 logRAD at 40 cm.

No patient referred any significant photopic phenomena post-surgery.

All patients declare that they have achieved independence from glasses for most of their daily activities.

These results show that IOL with controlled Positive Spherical Aberration provides an enhance depth of focus and an interesting near reading speed, in addition to spectacle independence and very good quality of vision in terms of patient satisfaction and absence of photopic phenomena.
