A compilation of questions related to keratoconus
1.Q: What are keratomileusis?
A: It is a non-surgical method to correct myopia at night with a rigid corneal contact lens. The lenses are worn at night to treat myopia, and during the day they are worn free of glasses or low prescription glasses, which can control the development of myopia in adolescents to some extent. It is recommended that this be done under the guidance of a physician or optometrist.
2.Q: How do keratocontact lenses treat myopia? What is the treatment principle?
A: Specially designed keratoplasty lenses are worn on the cornea to reduce the refractive power of the eye by producing a certain amount of pressure on the cornea to make the front surface flatter. By using the memory of the corneal shape, the central part of the cornea remains flat for a certain period of time after the lens is removed. The flattening of the cornea lengthens the focal length of the eye, allowing the focal point of the incoming light to shift from the front of the fundus to the retina, thus achieving the goal of treatment. Corneal tissue has “memory”. It tends to return to its previous state. Therefore, daily wear is required to maintain the treatment effect. Patients do not need to wear frames during the day to have good naked eye vision
3.Q: Who are the main users of keratomileusis?
A: The best correction is within -600 degrees, regular astigmatism is less than 150 degrees, irregular astigmatism is less than 100 degrees; suitable for people mainly under 18 years of age and some special occupations who can not perform laser surgery. Monocular myopia with keratomileusis can reduce binocular aberration and promote binocular monovision.
4.Q: What should I pay attention to before and after wearing the lens?
A: You should pay attention to personal hygiene. You should wash your hands before wearing and removing the lenses, master the correct method of wearing and removing the lenses, review the lenses on time, standardize the use of care products, and carry out all operations on a table with a white towel to avoid accidental dropping and damage to the lenses.
5.Q: What kind of situation can’t I wear keratomileusis?
A. Patients with severe dry eye, keratitis or other eye diseases; corneas that are too flat or too steep; pupils that are too large in diameter; patients who are too young, have poor personal hygiene and do not comply with treatment rules; and patients who have had myopic laser surgery are not suitable for wearing.
6.Will wearing keratomileusis damage my eyes or affect my vision?
A: Wearing keratoplasty lenses requires a certain degree of compliance and good hygiene habits, as instructed by the doctor or dispenser. First-time wearers will have a foreign body sensation, severe photophobia, tearing and other symptoms, but the situation will be quickly relieved by a few drops of artificial tears (new tears Ran eye drops).
7.Q: How to maintain the lens, clean, how long to wear every day?
A: First of all, the lenses must be cleaned before wearing, put in the mirror box to soak with a special care solution, cleaning the lenses when the force should be even, the mirror box should be cleaned once a day when taking the lenses must be light, careful. Wear 8-10 hours a day, not more than 12 hours.
8.Q: How long to wear a review?
A: The first day of wearing the lens to review, after no special circumstances can be in the first week, the first month in the morning off the lens to review, the next 5 months once a month to review, wearing the lens after six months, every 3 months to review.
9.Q: What are the advantages of keratomileusis?
Answer.
(1) No trauma;
(2) Easy to use;
(3) No special age limit (above 8 years old);
(4) Reliable results;
(5) It can control myopia deepening to some extent;
(6) No surgical risk.
10.Q: Do I need to continue wearing frame glasses after wearing keratomileusis?
A: After wearing the residual degree does not exceed 100 degrees, and into the corrective maintenance period, do not need to wear frame glasses. Residual degree of more than 100 degrees and the effect of correction is slow, the first need to wear low frame glasses.
11.Q: What should I pay attention to when removing glasses?
A: According to the degree of proficiency varies from person to person, generally first point 1 to 3 times artificial tears (new tears Ran eye drops), blink, confirm the lens in the cornea slide before you can remove the lens, do not force the suction stick to remove the lens.
12.Q: How long can I wear keratomileusis?
A: Theoretically, you can wear them for 3-5 years. If the lens is worn, lack of angle, deformation and other conditions that may damage the cornea, you need to listen to the doctor’s advice, timely replacement.
