Refractive surgical procedure when a lamellar disc from a donor cornea or commercial corneal lenticule is placed over the de-epithelialized host cornea and sutured into a prepared groove on the host cornea
Indications include aphakia, myopia and keratoconus
The technique is not commonly available due to:
Limited supply of human donor lenticule
Poorly predictable refractive outcome
Most patients require up to 1 year to achieve BCVA
Common irregular astigmatism because of possible distortions occurring with shaping and suturing the lenticule
