Purpose

To report the long term clinical experience following Femtosecond Intrastromal Lenticule Implantation (FILI) for management of moderate to high hyperopia.

Setting

Nethradhama Superspeciality Eye Hopsital, Bangalore, Karnataka, India

Methods

Eligible patients who underwent FILI for moderate to high hyperopia from July 2013 to October 2020 were included. A donor SMILE lenticule, matched for refractive error  was implanted into the recipient’s corneal pocket created using a femtolaser at 160 microns depth. Visual and refractive outcomes  and long term complications were evaluated at the end of a  mean follow-up of 68±17.28 months (5.6 years).

Results

42 eyes of 25 patients (mean age 27.29±5.52 years) were analysed. The mean SE reduced significantly from +5.5±1.96 to +0.66±1.17D at 68 months post-op. 71% (n=30) eyes were within ±1.00D of SE. Cumulative UDVA of 20/40 or better was achieved in 81% (n=34) of eyes. Efficacy and safety indices were 0.86±0.19 and 1.17±0.39, respectively. There was significant increase in Kmean anterior, central corneal thickness, Q-value, corneal HOAs and decrease in Kmean posterior 2 weeks post-op, without any significant change in these parameters thereafter, p >0.05. 4 eyes of 3 patients underwent enhancement and another 4 eyes underwent explantation of lenticule followed by exchange (2 eyes) and hyperopic LASIK (2 eyes). No eye lost >1 line of CDVA.

Conclusions

At 68 months, FILI for moderate to high hyperopia, showed good safety, efficacy and reversibility. Modification of nomograms and surgical planning  may be employed for further refinement of the outcomes.
