[Whether does the granular corneal dystrophy indicate for the excimer laser ablation surgery or not]

Area of Science:

• Ophthalmology
• Corneal Surgery
• Refractive Surgery

Background:

• Excimer laser technologies have advanced corneal refractive surgery, expanding indications.
• Procedures like PRK, LASEK, PTK, and LASIK have been used for granular corneal dystrophy with refractive errors, showing initial satisfaction.
• Concerns exist regarding recurrence and corneal opacity following these treatments.

Purpose of the Study:

• To clarify the exact indications for excimer laser keratectomy in granular corneal dystrophy.
• To present customized treatment nomograms for three types of granular corneal dystrophy.
• To guide the reasonable and correct application of excimer laser keratectomy for safe, effective, and long-term satisfactory outcomes.

Main Methods:

• Classification and diagnosis of three types of granular corneal dystrophy.
• Development of customized treatment nomograms for each dystrophy type.
• Application of excimer laser keratectomy based on the developed nomograms.

Main Results:

• Early positive results were observed with excimer laser procedures for granular corneal dystrophy.
• The study aims to address concerns of recurrence and corneal opacity.
• Customized nomograms are proposed to optimize surgical outcomes.

Conclusions:

• Refined indications for excimer laser keratectomy in granular corneal dystrophy are necessary.
• Customized treatment nomograms can improve the safety and efficacy of refractive surgery for this condition.
• Achieving long-term satisfactory results requires precise diagnosis and tailored surgical approaches.
