Refractive Surgery

04 July 2018/ Kategori : Health Corner /

Refractive errors, such as myopia, hyperopia and astigmatism, have been successfully corrected with Excimer Laser for two decades.

Persons older than 18 with myopia up to -12.0 Diopter, hyperopia up to +7.0 Diopter and astigmatism up to +.0 Diopter and with no change in the power of thecorrection glasses are examined by your physicians, and refractive errors can be corrected with Excimer Laser, if measurement data allows, no other eye disease is found and the corneal thickness is sufficient.

Retina should be examined in diabetic patients. Rheumatic diseases should be questioned. Patients wearing contact lens should stop using soft contact lens one week before the examination and using the gas permeable contact lenses three weeks in advance.

The examination addresses size of pupils, maps of anterior and posterior corneal surfaces, the refractive error and corrected and uncorrected visual acuities for near and distance vision. If monovision (leaving one eye myopic for the near vision advantage in one eye) is planned for the age above forty, vision trial is done. The dominant eye is determined. Next, drops are used that relax the eye muscles and the true refractive error is determined. General ophthalmic examination evaluates eyelid structures and eye muscles. Cataract is investigated in the lens, intraocular pressure is measured and the retina is examined. High-risk areas, such as retinal hole and detachment, are demarked and strengthened by Argon Laser. Excimer Laser treatment is employed a certain period after Argon Laser is applied.

The best method is selected by reviewing all examination results and taking into consideration the profession and the age of the patient; next, the decision of operation is made and the surgery is carried out in an appropriate time. Although mydriatic drops enlarge or dilate the pupils, they restore to the original form after a while.

No perfume should be used or eye makeup should be avoided in the operation day. Anesthesia is induced by anesthetic drops within 4 to 5 minutes. It is a pain-free procedure. Controls are repeated and the patient is worn ultraviolet-protection eyeglasses and asked to rest and not to touch the eye. The face should not be washed.

Postoperative care and hygiene is extremely important. The patient is informed in detail and asked to present for follow-up visit in the next day and the pre-planned intervals. Laser Surgery does not hinder possible future operations. It is necessary to avoid ball games for a certain period after the operation. Near and distance vision can be corrected in appropriate eyes.

An intraocular lens can be implanted for very high refractive errors. In such cases, additional examinations will be required.

If there is residue refractive error following cataract surgery and the examinations show acceptable results, they can be corrected with laser. It is appropriate to carry out the corrective surgery two months later in order to avoid fluctuation in the correction power.

Progressive bowing on the corneal surface requires careful follow-up.
