Purpose

To evaluate light and spectacle dependence, quality of vision, patient satisfaction after bilateral implantation of a non-diffractive, hydrophilic multifocal intraocular lens (IOL) with spiral optics: RayOne Galaxy® (Rayner, Worthing, UK) in Filipino patients at 1 month, 3 months, and 6 months after cataract surgery and to investigate the role of ocular surface health in over-all functioning and quality of vision

Setting

Prospective, single-surgeon, single-center study at the Eye and Vision Institute, The Medical City, Manila, Philippines

Methods

Adults above 18 years old underwent bilateral phacoemulsification and implantation of the RayOne Galaxy® IOL with an emmetropic target. At 1 month, 3 months, and 6 months after surgery, manifest refraction, uncorrected visual acuities at distance (UDVA), intermediate at 63cm (UIVA 63cm), near at 40cm (UNVA 40cm), and near at 33cm (UNVA 33cm) were measured. Spectacle and light dependence, quality of vision (QOV), and patient satisfaction were assessed using validated questionnaires. The ocular surface was evaluated using tear break-up time, tear break-up pattern, and corneal staining at all visits and managed with topical dry eye medications as indicated.

Results

The study has thirteen patients(n=26 eyes). At 6 months, mean spherical refraction(±SD) is -0.24(±0.71) diopters. Mean(±SD) binocular UDVA, UIVA 63cm, UNVA 40cm, and UNVA 33cm are -0.15(±0.16), 0.28(±0.09), 0.13(±0.03), and 0.10(±0.08)logMAR. Mean QOV is 90.3/100 at 6 months from 86.7/100 at 1 month with glare as the most reported dysphotopsia. Spectacle/light dependence scores for distance/near activities (never 1.00 to always 5.00) are: 1.21 from 1.30 for spectacles, 1.29 from 1.41 for light, and 1.10 from 1.33 over-all. For patient satisfaction, 92% are happy with the surgical outcome, 92% would select the same lens, and 92% would recommend the surgery to a relative/friend. Ocular surface parameters improved from 1 month to 6 months.

Conclusions

Patients bilaterally implanted with the RayOne Galaxy® IOL have low light and spectacle dependence for distance and near activities, minimal levels of dysphotopsia, and high over-all satisfaction. Furthermore, general improvement in functioning and quality of vision is observed from 1 month to 6 months after surgery which may be attributed to better ocular surface health in addition to neural adaptation.
