To evaluate the safety, effectiveness and predictability of allogeneic corneal len inlays to correct hyperopia using smile incision femtosecond lenticule extraction (Visumax, Zeiss Inc, Germany).
Ophthalmic Center, Beijing Tongren Hospital, Capital Medical University, Beijing Ophthalmology & Visual Sciences Key Lab, Beijing, China.
Allogeneic corneal len inlays was performed to correct 7 patients with moderate hyperopia, and uncorrected and best corrected visual acuity, refraction, optical coherence tomography (OCT) and corneal biomechanics were analyzed.
There was no complication during and after operation. Uncorrected distance visual acuity increased 2 or 3 lines one day and one month after surgery, and near visual acuity improved from J4 to J2 and the spherical equivalent (SE) was improved from +6.44D to -0.435D one month after surgery. The cornea was clear and transparent, and the graft was centered in the corneal stroma capsular bag without rejection, showing by OCT one month after surgery. The corneal biomechanics indicators, such as corneal hysteresis (CH) and corneal resistance factor (CRF) did not significantly change one month after surgery.
Allogeneic corneal len inlays using smile incision femtosecond lenticule extraction can be used to correct hyperopia with good safety, effectiveness and predictability.
