ABSTRACT

Objective:

To study the clinical outcome of lamellar keratoplasty combined with autogenous corneal stromal padding for treatment of corneal perforation.

Methods:

An observational case series study was conducted.A total of 14 patients (14 eyes) with corneal perforation underwent lamellar keratoplasty in Henan Provincial People's Hospital from January 2017 to August 2018 were collected.During the operation, the corneal stromal autograft was taken to pad the corneal perforation.Visual acuity, intraocular pressure, corneal epithelial healing time, infection recurrence, and the status of corneal graft and anterior chamber were recorded on the 1st, 7th, 14th day, 1st, 3rd, 6th, 9th and 12th month after operation.OCT examination of anterior segment was performed at 1 month, 6 and 12 months postoperatively to observe the interlamellar structure of corneal implantation bed and stromal graft, anterior chamber and iris.The safety and effectiveness of the operation were evaluated according to the 1-year follow-up.The study protocol adhered to the Declaration of Helsinki and was approved by the Ethics Committee of Henan Eye Hospital (No.HNEECKY-2019[18]). Written informed consent was obtained from each patient prior to entering the study cohort.

Results:

The healing time of corneal epithelium was 2-4 days after operation, (3.01±0.59) days on average.At one day after surgery, all patients had normal anterior chamber depth without aqueous leak and no double chamber was observed.The corneal grafts attached to the implantation bed well and showed mild to moderate edema.There was no recurrence of corneal infection ulcer two weeks after operation, and the corneal ulcer was healed and anterior chamber was well formed in 14 patients.The corneal graft was transparent, and the anterior segment OCT image showed corneal implant bed and graft were well attached, and the anterior chamber depth was normal three months after operation.The best corrected visual acuity of 9 eyes was more than 0.3 one year after operation, and the vision acuity of the 14 patients improved obviously, and no refractory glaucoma occurred after operation.

Conclusions:

Lamellar keratoplasty combined with autogenous corneal stromal padding is a safe and effective surgical procedure for treating corneal perforation.
