What is cross-linking cornea?
In this method, the corneal arrays of the cornea are connected with the help of ultraviolet rays and in the presence of riboflavin to make the cornea stronger.What volunteers are suitable for cross-linking? The best volunteers of this method are:

Patients who have recently been diagnosed with keratoconus

Young and middle-aged people whose disease is progressive

Also, those who have a contact lens do not fit well on their eyes.

The patient should have a definite diagnosis of keratoconus and documented evidence of disease progression.

The thickness of the cornea should be at least 400 microns.

The patient should not be pregnant or breastfeeding.

How is it done? This procedure is performed under local anesthetics using an anesthetic droplet. The patient lays on the bed in the operating room and under sterile conditions. By inserting a special device, the eyelids are kept open. After removing the cornea cell surface (epithelium), riboflavin drops for thirty minutes (once every 3 minutes). Percentage is cast into the eye, and then, within the next thirty minutes, once every 5 minutes, the drop is in the eye, ultraviolet radiation (ultraviolet) is shifted to the cornea (in newer methods, the intensity of radiation and the duration of radiation Dropped to 5 to 10 minutes). At the end of the treatment, the lens touches the dressing on the surface of the cornea and the patient comes down from the bed with the eye open. Antibiotic drops, anti-inflammatory, artificial tears and analgesics are prescribed and the patient is discharged. This will increase the cross-links between the corneal collagen strands (as shown below) and, as a result, increase corneal strength.

What is the schedule of post-operative visits and examinations? The day after the operation, the patient is examined for how the cornea is restored and the possibility of infection. Day 3 or 4 If the cornea is improved, the contact lens will be removed. The next visits will be at intervals of one month, three months, six months, one year and two years.

How long does the person return to work and normal life? The patient will return to work 3-4 days after surgery. During this time, be careful not to let water enter your eyes. During the first few weeks of surgery, visual acuity may be a little bit worse than before. You can resume contact lens after six weeks.

Can both eyes work in one session? Some surgeons prefer to have an eye on each session, but both eyes can be operated in one session.

What are the possible side effects of this procedure? External body sensation, irritation, and irritation are common on the first day of surgery. Pain and discomfort are controlled in the first 24 hours. Another possible complication is eye dryness, which sometimes may require artificial tear drops a few months after surgery. What are the results of cross-linking? Three to five years old studies have reported that disease progression has stopped in about 100% of the cases, and in half of the cases the cornea has slightly flattened or a slight disease (about 2.87 diopters) has been improved. And the improved vision of the 1.4 line has been improved. This method does not require corneal transplantation or is delayed. In this method, which is currently the newest method for treating corneal ankylosis, unlike other therapies, in most cases, not only is the progression of the disease prevented, but the vision of the individual with and without glasses is improved and the amount of astigmatism is significantly reduced Will have.
