Abstract Details

Purpose:

To assess dry eye rates, visual outcomes and safety of the Raindrop Near Vision Inlay implanted under various femtosecond laser flap thicknesses.

Setting:

Coastal Vision, Long Beach CA, USA

Methods:

Prospective, multicenter, case series from the US IDE Study. Emmetropes (-0.5 to +1.0 D MRSE) were implanted with the Raindrop Inlay in the non-dominant eye under various femtosecond flap thicknesses. Group A (n=30) with flaps in the range of 32% to 34% of central corneal thickness (CCT), group B (n=180) with flaps of 29% to 31% of CCT, and group C (n=30) with the thinnest flaps between 24% to 28% of CCT were compared. ETDRS visual acuities at various distances, visual symptoms, ocular discomfort (dryness), and cornea clarity were evaluated at 1M, 3M, 6M, and 12M.

Results:

Monocularly in the inlay eye at 12M, mean UVAs were similar for all groups at near (A: 20/20, B: 20/20, C: 20/21) and distance (A: 20/22, B: 20/23, C: 20/22). All groups maintained high patient satisfaction (A: 93%, B: 92%, C: 87%) and low reports of moderate or worse ocular dryness (A: 3%, B: 4%, C: 0%). Groups A and B showed less corneal reaction with 93% and 94% of patients with clear corneas (no haze) respectively. Group C was slightly lower at 87%.

Conclusions:

Thicker femtosecond flaps did not increase moderate or worse dry eye, and these patients obtained equally satisfactory near and distance uncorrected vision. Furthermore, subjects with thicker flaps tend to show less corneal reaction.
