Treatment of Irregular Cornea
Do you have poor sight due to scars on your cornea?
A sophisticated treatment called Sequential Customized Therapeutic Keratectomy could be the perfect solution to giving your sight back without the need for other more complex surgeries such as a corneal transplant.
This is also an ideal treatment for many patients with hereditary corneal dystrophies such as lattice dystrophy, Avellino dystrophy, Granular dystrophy, Reis-Bucklers dystrophy and epithelial basement membrane dystrophy.
What is Sequential Customized Therapeutic Keratectomy?
What to Expect
On the Day of Your Treatment
Steps 3 - 4 are repeated until the cornea is as regular as possible
1. Warm welcome
2. Ensuring you are comfortable
Local anaesthetic eye drops will be used to ensure your eyes are completely numb and comfortable throughout the procedure.
3. Wave-front measurment
You will have a 3D scan of your eye with our advanced topographer/tomographer. The scanner calculates a sophisticated treatment algorithm for the laser to treat your eye.
4. TransPRK laser treatment
The laser effectively and precisely changes the shape of the cornea to decrease corneal irregularities and remove any scars you have on your cornea. A contact lens will be placed on your eye.
After the Treatment
1. What to Expect
The eye will be very sore and uncomfortable soon after the procedure. The vision will be blurry and light sensitive until the surface skin grows back. Your eye and the vision should feel much better after 2-5 days.
2. Aftercare drops and advice
You will be given aftercare drops and advice. You will also be given pain killer medications to take for 2 days. You will be asked to lie down in a dark room with your eyes shut for most of the next 2 days to speed up the recovery. Avoid putting makeup on your face for one week and on your eyes for 2 weeks following your vision correction surgery.
3. The future
You will be seen in the next 2-5 days. You should be able to resume most normal activities and sports within 2-4 weeks. As part of our unique service you will be given Dr. Arbabi’s personal phone number so you can call or WhatsApp him directly if you had any concerns or want to discuss anything about your procedure.
How is the procedure carried out?
In Sequential Therapeutic Customized Keratectomy (SCTK) treatment Dr. Arbabi uses the advanced Schwind AMARIS laser machines with one of the most sophisticated topography and wave front analysers . These sophisticated scans give an accurate 3D map of the path of light from front to the back of the eye, highlighting where these irregularities exactly lie. The scanner calculates a sophisticated treatment algorithm for the laser.
You will have a laser eye treatment based upon above complex calculation. Dr. Arbabi will take you back to the scanner for further measurement. If the cornea continues to have significant irregularities on scan, the laser will be repeated again. This cycle is repeated until the cornea is as regularised as possible. This complex technique is not widely available. Dr. Arbabi had to go and learn this technique from its pioneers in Milan, Italy.
Dr Arbabi is a very kind, compassionate and highly recommended surgeon. He really puts patients at ease and help you through every step of your journey towards a better sight
