First Experience Of Slike Procedure: Implanting Autologous Lenticule Obtained By Smile For Hyperopia.

To evaluate the safety, effectiveness, stability, and predictability of implanting autologous lenticule obtained from small incision lenticule extraction implanted inside an intrastromal pocket for the treatment of hyperopia.

«Astana Vision» clinic, Astana city, Republic of Kazakhstan.

A SMILE procedure using the VisuMax femto-second laser (Carl Zeiss Meditec, Jena, Germany) was performed on a patient with moderate myopia right eye and the extracted lenticule was stored (MRSE -5.00 diopter, optical zone 6.70 mm, central lenticule thickness 108 μm). In the left eye (MRSE +5.25 diopter with BCDVA 0.60(20/32), a pocket lamellar incision was created using the VisuMax SMILE software. The interface was separated and the autologous lenticule was inserted through the small incision. Follow-up was at 1 day, 1, 3, and 6 months postoperatively. Patient received a complete ophthalmologic examination at each visit. 

Six month postoperatively, autorefraction was +0.25 -0.75 × 57°. Mean keratometric power increased by 4.87 diopters. Central corneal thickness by Oculyzer, (WaveLight Oculyzer II, Germany) increased by 81 μm. The cornea remained clear over the 6 month postoperative period. UCDVA at 6 m was 0.50, BCDVA was 0.60 (20/32). We are planning enhancement of visual outcomes with PRK procedure.

Implanting an autologous lenticule obtained by small incision lenticule extraction for hyperopia might be safe, effective, and stable, but its predictability should be improved in the future.
