Corneal Scraping
About the procedure
Corneal scraping is a diagnostic procedure performed to obtain superficial material from the cornea for microscopy, culture, and sensitivity testing when an infection is suspected. It is used to identify causative organisms in infectious keratitis, including bacterial, fungal, or Acanthamoeba infections, to guide targeted therapy. The procedure is performed under topical anaesthesia at the slit lamp or in a sterile theatre using a blade or spatula to scrape the affected area. Samples are placed on slides and culture media, and treatment begins promptly based on preliminary or culture results.
Care before the procedure
- Avoid using eye drops unless prescribed by your ophthalmologist.
- Do not rub or touch the affected eye before the procedure.
- Inform the doctor about allergies or previous eye surgeries.
- Arrange for someone to accompany you if anaesthesia affects your vision.
Care during the procedure
- Keep your head still and follow instructions at the slit lamp.
- Blink minimally while the doctor collects the corneal sample.
- Report any sudden pain or discomfort immediately during the procedure.
- Maintain eye closure when requested to allow precise sampling.
Care after the procedure
- Use prescribed antimicrobial eye drops as directed by your doctor.
- Control pain with recommended medications and avoid rubbing the eye.
- Attend all follow-up visits to monitor healing and infection resolution.
- Protect the eye from dust, water, or trauma during recovery.
Eligibility
- Individuals with suspected infectious keratitis not responding to empirical treatment requiring precise pathogen identification for targeted therapy.
- Patients presenting with corneal ulcers or stromal infiltrates where microbiological confirmation is essential before starting intensive therapy.
- Contact lens users with persistent corneal pain, redness, or vision changes suspicious for microbial keratitis.
- Individuals with recurrent corneal infections or atypical presentations where culture or PCR is needed for definitive diagnosis.
