Summary
Phototherapeutic keratectomy (PTK) effectively treats various anterior corneal disorders, including scars, dystrophies, and lesions. Emerging research continues to explore its applications and refine outcomes for conditions like bullous keratopathy.
Area of Science:
- Ophthalmology
- Corneal Surgery
Background:
- Phototherapeutic keratectomy (PTK) is a surgical excimer laser procedure.
- It is used to treat superficial corneal irregularities.
Purpose of the Study:
- To review recent publications on the use of phototherapeutic keratectomy (PTK).
Main Methods:
- Literature review of recent publications on PTK.
Main Results:
- PTK shows beneficial outcomes for anterior stromal scars, epithelial and anterior stromal dystrophies, and elevated corneal lesions.
- Studies evaluate biomechanical properties post-PTK for granular corneal dystrophy to prevent ectasia.
- PTK is the most effective treatment for recurrent corneal erosion syndrome.
- In developing regions, PTK is a common treatment for bullous keratopathy while awaiting penetrating keratoplasty.
Conclusions:
- Phototherapeutic keratectomy (PTK) successfully treats diverse anterior corneal conditions.
- Ongoing research may broaden the clinical applications of PTK.
