A technique for preparing corneal lamellar donor tissue using simplified keratomileusis

Area of Science:

• Ophthalmology
• Corneal Surgery
• Refractive Surgery

Background:

• Refractive keratoplasty, while complex, aims to correct vision through corneal reshaping.
• Lamellar keratoplasty involves transplanting thin layers of corneal tissue.
• Current methods for preparing lamellar tissue can be intricate and time-consuming.

Purpose of the Study:

• To describe a modified keratomileusis technique for producing lamellar buttons from donor corneas.
• To simplify the preparation of planopower corneal discs for refractive keratoplasty.
• To enhance the accuracy and efficiency of lamellar tissue preparation.

Main Methods:

• Utilizing a modified keratomileusis technique to create lamellar buttons.
• Focusing on the production of planopower corneal discs.
• Comparing the accuracy of keratomileusis to free-hand dissection for lamellar tissue preparation.

Main Results:

• The modified keratomileusis technique offers a simpler approach to producing lamellar buttons.
• This method potentially provides greater accuracy in preparing lamellar tissue of known thickness.
• The technique is expected to yield improved visual results compared to free-hand dissection.

Conclusions:

• Modified keratomileusis is an effective technique for producing accurate lamellar buttons.
• Pre-cutting and storing lamellar buttons of various thicknesses by eye banks can streamline operating room procedures.
• This approach holds promise for improving efficiency and outcomes in lamellar keratoplasty.
