Even if you have never worn glasses or lenses in your life, after 40 you may need them. Presbyopia, or hyperopia, is a natural change. Previously, the only way to improve vision in this condition was with reading glasses or bifocal lenses. Modern ophthalmic surgery has developed techniques for the treatment of presbyopia. The Clinic for Laser Eye Microsurgery offers a special LASIK mode to correct age-related hyperopia.
The essence of the procedure
The idea of the unique technique “monovision” is to separate the functions of the eyes: one will see well at a distant distance, the other – near. The ophthalmologist selects the dominant eye and corrects distant vision, and the second deliberately makes it myopic. Thanks to this, with the first eye, the patient can confidently see in the distance, with myopic one – he can distinguish objects well near. This solution involves some compromise – distance vision remains imperfect, but nevertheless does not prevent a person from performing their usual activities without glasses. Most patients don’t even notice it.
Another LASIK technology for treating presbyopia works on the principle of multifocal glasses, the lenses of which include several zones: for far and near vision. The surgeon uses an excimer laser to create similar zones in the cornea: one allows you to see clearly in the distance, and the other is responsible for reading. Multifocal lenses can move and distort the picture. LASIK, by contrast, guarantees stable vision.
After surgery, 91% of patients do without glasses or lenses. In rare cases, reoperation is required years later. Some patients after a multifocal lasik are less able to distinguish colors or see a halo at night, but these are temporary phenomena that disappear within six months.
