A standardized drawing scheme to document corneal changes following refractive corneal surgery

Area of Science:

• Ophthalmology
• Corneal Surgery
• Refractive Surgery Documentation

Background:

• Accurate documentation of corneal changes is crucial for managing outcomes after refractive surgery.
• Existing methods may lack standardization, leading to ambiguity in recording post-operative corneal alterations.

Purpose of the Study:

• To introduce a systematic and standardized drawing scheme for documenting corneal changes.
• To ensure unambiguous and reproducible recording of results following incisional, coagulative, and excimer laser corneal surgeries.

Main Methods:

• Development of a standardized drawing scheme using five distinct colors.
• Application of symbols to represent specific corneal conditions after procedures like radial keratotomy, laser thermokeratoplasty, photorefractive keratectomy, and LASIK.
• Documentation of corneal changes in both frontal and sectional views.

Main Results:

• Corneal changes resulting from various refractive corneal surgical techniques were systematically documented.
• The scheme effectively captured alterations following incisional, coagulative, and excimer laser procedures.

Conclusions:

• The proposed drawing scheme allows for clear and unambiguous tracking of specific corneal features in clinical practice.
• Enhances the reproducibility and standardization of corneal change documentation post-refractive surgery.
