Abstract Details

Purpose:

To evaluate refractive outcomes of distance, intermediate and near visual acuity after bilateral implantation of RayOne trifocal lens (Rayner) in 21 patients within 3 months.

Setting:

Eye Centre Prague, Prague, Czech Republic

Methods:

In this prospective study 42 eyes of 21 patients were evaluated. In 5 patients (10 eyes) PRELEX surgery was performed and in 16 patients (32 eyes) cataract surgery was performed. The trifocal lens was implanted in both groups of patients. Patients with amblyopia or other ophthalmic pathology which would affect the quality of postoperative vision were not included. LRI (limbal relaxing incision) was performed in 10 cases to reduce corneal astigmatism. The patients were postoperatively evaluated for uncorrected distance (UCDVA), intermediate (UCIVA) and near (UCNVA) visual acuity monocularly and binocularly. Postoperative spherical refraction and astigmatism were also evaluated.

Results:

The postoperative sphere refraction was in negative values from -1.50D to -0.25D in the 29 eyes, zero refraction was measured in 3 cases and 9 results were positive (up to +1.50D). 1 eye failed to measure refraction. The negative values of the spherical refraction are attributed to the optical surface of this trifocal lens. The mean postoperative astigmatism was 0,69±0,43D. The average monocular UCDVA was 1,01±0,13D and binocular UCDVA was 1.12±0,13D. The mean UCIVA was 1.08±0,19D monocularly and 1.26±0,12D binocularly. The mean monocular UCNVA was 0.96±0,12D and 0.99±0D binocularly.

Conclusions:

The RayOne trifocal lens provides quality vision at all distances without the need for spectacle correction. Patients reported low incidence of photic phenomena disturbance and high level of quality of life.
