Inadequate Results for Microkeratome-assisted Additive Stromal Keratoplasty for Management of Keratoconus

摘要: PURPOSE To evaluate a new automated technique--microkeratome-assisted additive stromal keratoplasty (MASK)--for the management of keratoconus in eyes scheduled for surgery with clear cornea associated total contact lens intolerance. METHODS This non-comparative, interventional case series included four patients stage I and II The first step surgical procedure consisted performing nasal-hinged flap on host microkeratome. second extracting piano-powered disk from donor's using an artificial chamber. 80-microm thick lamellar graft was punched 7.5-mm circular trephine positioned beneath flap. Corneal refractive end sixth postoperative month. RESULTS No corneal performed after 6 months follow-up. Only one eye gained five lines best spectacle-corrected visual acuity (BSCVA). Among other three eyes, two had unchanged BSCVA lost line BSCVA. At surgery, mean thickness increased by 148.75 microm. CONCLUSIONS Microkeratome-assisted appears to be safe straightforward technique that preserves endothelium avoids need open-sky procedure. However, our study, MASK is not considered as alternative penetrating or deep because imprecise anatomic outcomes.
