Contact lenses
|
Benefits |
Drawbacks |
-
Vision in contact lenses is more natural compared to spectacles. Objects sizes are not distorted;
-
Contact lenses move with eyes therefore there are no image distortions like with spectacles;
-
Contact lenses used for vision correction do not affect appearance;
-
They never fog;
-
Side vision is not limited;
-
Suitable for those who have vision difference between the eyes over 2.0 D.
|
-
They are in direct contact with the eye cornea, therefore they can damage cornea or provoke corneal deceases;
-
Use of contact lenses demands regular check-ups by an ophthalmologist;
-
They do not replace spectacles completely. At least one pair of specs will be needed as a supplement for lenses;
-
Contact lenses have to be removed daily, and thoroughly disinfected. Prolonged wear lenses can not be recommended for most patients;
-
When contact lenses are used an eye winker will cause pain and will demand to remove the lens and put it back again. Or you will have to use spectacles;
-
Contact lenses have to be renewed regularly.

Laser vision correction
|
Benefits |
Drawbacks |
-
Restores the ability to see everything with own eyes;
-
Correction results have all the benefits of good natural vision;
-
Eliminates all drawbacks of vision improvement aids (spectacles and contact lenses);
-
Correction itself and the adaptation period after it are painless;
-
Ensures the required results with minimal risk of side effects;
-
Very short recovery period (already several hours after correction good vision is restored);
-
Laser correction is an outpatient procedure, no admittance to hospital required;
-
According to long-term patients observations, laser correction does not cause vision deterioration.
|
-
There are age limitations. As eyes keep developing in childhood and adolescence period, vision may change with time, therefore Excimer-laser correction is recommended only after 18;
-
Laser correction cannot manage age-related hyperopia (presbyopia);
-
When it is performed after 40-45 the necessity to use spectacles for short/reading distance remains actual;
-
There are some contra-indications (certain eye and general deceases, individual eye structure features, etc.)
