Stromal Lenticule Implantation for Management of Herpetic Stromal Keratitis

Not Applicable

• Conditions: Stromal Keratitis

• Registration Number: NCT05156151
• Lead Sponsor: Eye Hospital Pristina Kosovo

Brief Summary

The aim of this study is the evaluation of corneal transparency and improvement of visual acuity in patients with herpetic stromal keratitis.

Detailed Description

Stromal keratitis is an infectious ocular disease of either necrotizing or non-necrotizing form, due to an HSV infection, and characterized by corneal stromal necrosis, inflammation, ulceration and infiltration by leukocytes.

In our study these early findings suggest that the use of corneal stromal lenticules with stromal stem cells and live keratocytes could be a safe and efficient treatment for stromal scar after herpetic keratitis, and excluding the recurrence of the disease by removing the corneal scar after herpetic infection using Smile and implanting the lenticule equal to the volume of the removed scar tissue.

Stromal lenticule implantation is relatively simple, low-cost and offers advantages over corneal transplantation as a definitive procedure in the treatment of this disease.

Primary Outcome Measures

Name	Time	Method
Corneal transparency	12 months	Implantation of corneal stromal lenticules with stromal stem cells, live keratocytes and telocytes, stromal haze and scar have been successfully treated and stabilized the biomechanical stability of cornea in 87% of the patients which underwent this treatment.

Secondary Outcome Measures

Name	Time	Method
Evaluation of visual acuity	12 months	Implantation of fresh corneal lenticule resulted in the visual acuity according to the clarity of cornea.
