About the clinic
Laser iridotomy at the clinic of Dr. Nikolaos I Dervenis in Thessaloniki, Greece, treats narrow-angle glaucoma and prevents sudden vision loss. This procedure uses an anterior segment laser to create a tiny hole in the iris. This opening allows fluid to flow correctly and lowers eye pressure. The clinic specializes in advanced eye surgeries under the direction of a London-trained surgeon.
Procedure Details and Method
Laser iridotomy is a common treatment for patients at risk of angle-closure glaucoma. The procedure uses a focused anterior segment laser beam. The surgeon creates a microscopic drainage hole in the outer edge of the iris. This helps balance the pressure between the front and back of the eye. It is a quick outpatient treatment that helps avoid permanent damage to the optic nerve.
The procedure generally includes several steps:
- Numbing eye drops are applied to make the treatment comfortable.
- A special lens is placed on the eye to focus the laser beam.
- The anterior segment laser makes the necessary opening in the iris.
- Anti-inflammatory drops are used after the session to manage swelling.
Expertise in Ophthalmic Surgery
Care at the clinic is led by Dr. Nikolaos I Dervenis, a Consultant Ophthalmic Surgeon. Dr. Dervenis brings experience from his training at prestigious UK institutions. He completed his specialized training at Moorfields Eye Hospital and Western Eye Hospital in London. These facilities are known globally for their high standards in eye care and surgical innovation.
Dr. Dervenis holds multiple advanced degrees, including an MSc and a PhD. He is also a Fellow of the European Board of Ophthalmology (FEBO). This qualification shows he meets the highest European standards for ophthalmic practice.
