A. The nature of keratomileusis.
Corneal shaping lens is a non-surgical myopia correction method, belongs to the national tertiary medical equipment need to be under the guidance of a physician or optometrist for fitting.
Second, the main effect of keratomileusis.
1, keratomileusis mainly for the rapid growth of myopia in adolescent patients, can effectively curb the rapid deepening of their myopia.
2. By wearing them at night while sleeping, the eyes can have good naked eye vision without any glasses during the day.
Corrective process of keratoconus
Treatment is divided into two main phases.
(a) The first two months are the treatment period; during this period, the physician or optometrist closely follows the patient’s condition and adjusts the treatment plan in a timely manner, including the wearing method, the length of wearing time, and the need for additional supplementary medication. (a) Patients are required to follow up and cooperate with the treatment on time according to the regulations and medical prescriptions.
(ii) After the completion of the treatment period, the orthodontic process enters the maintenance period, and depending on each individual’s situation, patients need to wear lenses for a period of time every day or every other day to maintain the treatment effect. Patients should have a follow-up visit on time, stop wearing them automatically when they encounter abnormal conditions, order their own antibiotic eye drops and contact their physician or optometrist in time.
Four, our hospital carried out the dream David keratomileusis project.
Mondial keratomileusis suitable for people
1, low myopic patients with high bare eye vision requirements.
2, no corneal abnormalities, such as inflammation, degeneration, etc., no other diseases of the eye.
3, understanding the mechanism of action of keratomileusis and its potential complications and limitations of correction.
4, clear motivation and very good compliance.
5, generally 7 years of age or older, with some ability to care for themselves and with parental supervision.
6, myopia in the range of -0.75 to -6.00D, astigmatism below -1.50D, and cis-regular astigmatism, and generally poor results with retro-regular astigmatism; especially recommended for patients below -4.00D.
7, corneal curvature range of 41.00D~45.50D is good, too large and too small correction difficulties.
8, adolescents with progressive development of myopia.
9.Patients who have a certain financial base and can bear the cost of lenses and other expenses during treatment.
Mondial keratomileusis fitting contraindications
1, there are certain misconceptions about keratomileusis treatment, such as patients who unrealistically believe that the method can cure myopia.
2, expectations are too high and do not correspond to the actual effect of keratomileusis.
3, eye diseases, such as patients with diseases on the eye surface, epithelial cell stromal membrane degeneration, endothelial cell degeneration, patients with recurrent epithelial cell spotting and severe dry eyes, patients with infections and inflammatory eye diseases, etc.
4, refractive error greater than -6.00D, astigmatism for retroglaucoma, astigmatism greater than -2.00 is not suitable for night wear.
5, patients with significant intraocular astigmatism, and those with refractive irregularities with a spherical to column lens ratio less than 2 need to be considered with caution
6, patients with large pupils, especially those with larger pupils at night (>4mm)
7, young age, poor self-care ability and poor personal hygiene habits.
8, those who cannot complete the follow-up operation, and those with poor compliance in fitting and follow-up.
