Purpose

To evaluate visual and optical performance in patients having bilateral surgery with a Hydrphobic intraocular lens (IOL) (RAO 800 C, Rayner) and micro-incision technique 2.2 ( RayOne injector, Rayner)

Setting

Unità Operativa di Oftalmologia, A.R.N.A.S. Ospedali Civico Di Cristina Benfratelli, Palermo, Italy

Methods

Forty patients (80 eyes) were evaluated after implantation of hydrophobic monofocal IOL (RAO 800 C, Rayner). Uncorrected visual acuity for far (> 4 m), intermediate (70 cm) and near (40 cm) distance, mean spherical equivalent (SEQ) and photopic and mesopic contrast sensitivity were assessed postoperatively with a minimum follow-up of 6 months. The biometric target was emmetropia. Glistening evaluation with Miyate scale and posterior capsule opacification (PCO) were reported at 6 months. The results were compared with a control group of 40 patients (80 eyes) implanted with another hydrophobic IOL (Clareon, Alcon).

Results

All eyes achieved uncorrected distance visual acuity (UCVA) of 0.10 logMAR or better at 6 months postoperatively. No differences were found in both groups regarding uncorrected intermediate (UIVA) and near (UNVA) visual acuity. Postoperative refraction was similar in both groups without statistical differences. Postoperative contrast sensitivity was within normal limits under photopic and mesopic conditions at any spatial frequencies. Dysphotopic phenomena were infrequent and mild in both groups and postoperative satisfaction was high in all cases. PCO and glistening incidence were low in all patients. 

Conclusions

RAO800C showed stable and excellent results in terms of refractive outcomes. The values show a safety and reliable result of the hydrophilic lens in object, in terms of optical transparency and quality of the material. The optical design allows a very reliable barrier against PCO. This technology provide excellent performance in terms of quality of vision with no dysphotopic phenomena, improving visual quality and patient satisfaction.
