简要总结
Preoperatively, slit lamp examination/anterior segment OCT will be done to know the depth of the opacity and for the purpose of documentation. Patients will be divided into two groups by computer generated randomization. In the first treatment arm, patients will undergo microkeratome-assisted anterior lamellar keratoplasty in main OT. In the second treatment arm, patients will undergo femtosecond laser-assisted anterior lamellar keratoplasty in Femto OT. Patients will be followed postoperatively on the next day, after 1 week, after 1 month, after 3 months and after 6 months.
