Abstract Details



Purpose:

To assess visual function in pseudophakic patients treated with a transparent hydrogel corneal inlay (Raindrop) to improve near and intermediate vision

Setting:

(1)Coastal Vision, Long Beach CA, USA, (2)Laser Ocular Hidalgo, Monterrey, Mexico, (3)Codet Vision Institute, Tijuana, Mexico, and (4)Ho Chi Minh City Eye Hospital, Vietnam

Methods:

Thirty-five subjects previously implanted with standard monofocal IOLs for cataract were identified and treated in the non-dominant eye with Raindrop, a near vision corneal inlay that creates a central corneal steepening (Profocal cornea) to increase the range of vision. Thirteen subjects were also treated with LASIK concurrently to correct for ametropia. Uncorrected and best distance-corrected visual acuities at 3M will be reported based on standard measurement methods while patient satisfaction, visual function, and any visual symptoms will be assessed using a questionnaire.

Results:

Thirty-three patients were examined at 3 months at which point, on average, subjects achieved binocularly 0.1 UNVA, 0.1 UIVA and 0.0 UDVA logMAR. When tested monocularly, average UNVA remains 0.1 logMAR. Best corrected near and distance vision in the inlay eye were, on average, within 0.02 logMAR of pre-op and no patients lost two or more lines. Near, intermediate and distance task performance improved under good light and dim light conditions when compared to pre-op. Eighty-five percent of patients were ‘Satisfied' or ‘Very Satisfied,' 12% were ‘Neutral', and 3% were ‘Dissatisfied.'

Conclusions:

Raindrop changes the shape of the cornea to improve near, intermediate and distance (when combined with LASIK) functionality. In this cohort of pseudophakic patients implanted with standard monofocal IOLs, the transparent inlay improved visual acuities and task performance significantly.
