Abstract
- AIM: To investigate the preliminary clinical observation of excimer laser phototherapeutic keratectomy(PTK)assisted by anterior segment optical coherence tomography(OCT)in the treatment of non Ⅱ type granular corneal dystrophy. METHODS: A retrospective case series were studied. Totally 8 patients(12 eyes)who were diagnosed as granular corneal dystrophy underwent PTK from April 2011 to January 2013 in our hospital. All patients were excluded from the Ⅱ type granular corneal dystrophy(Avellino corneal dystrophy)by the Avellino corneal dystrophy rapid diagnostic kit and underwent preoperative anterior segment OCT examination, so as to determine the lesion morphology and depth, and used to guide the setting of PTK parameters. They were followed up for the complications after operation, postoperative recurrence, the recovery of visual acuity. RESULTS: All patients were followed up for 6-12mo, average 9mo after operation. All patients' best corrected visual acuity were significantly improved, superficial corneal opacity lesions were effectively removed, and the corneal opacity recurrence or serious Haze were not found during the follow-up period after operation. CONCLUSION: In patients with non type Ⅱ granular corneal dystrophy, PTK assisted by anterior segment OCT can be accurate, effective removal of corneal lesions, obtain good effect after operation.
