The use of contact lenses plays an important role in the treatment of refractive errors such as myopia, hyperopia and astigmatism.
With the advancement of technology, major advances are being made in the material, shape, design and surface coating of contact lenses. Contact lenses, which are used for different purposes, from eliminating refractive errors to preventing the progression of myopia, make significant contributions to patient comfort. However, for the right lens selection, experienced experts in this field should be consulted. Professor of the Eye Diseases Department of Memorial Ankara Hospital. Dr. Koray Gümüş gave information about the properties and uses of contact lenses.
New generation contact lenses are much safer and more comfortable
Patients who do not want to use glasses for the treatment of refractive errors in the eye generally prefer to use contact lenses. The oxygen permeability is increased by making a serious change in material properties; Contact lenses, whose design, water content, edge structures and surfaces have been updated significantly, provide a safer, longer and more comfortable use for patients.
It is mostly preferred for correction of myopia and hyperopia defects.
Today, contact lenses are mostly preferred to correct refractive errors such as myopia and hyperopia. However, with the increase in the population over the age of 45 and the deterioration of near vision becoming more common all over the world, new generation multifocal contact lenses have started to be produced. These lenses ensure that patients can see both near and far, and they do not need glasses in their daily activities.
If you have astigmatism, the solution is toric contact lenses!
Astigmatism is a refractive error that is quite common among eye defects but is generally assumed to be absent when wearing contact lenses. It is possible to provide patients with a much higher quality vision with toric contact lenses, which eliminate astigmatism that causes headache and eye fatigue. Therefore, the use of toric contact lenses should be recommended to patients with astigmatism.
Corneal wounds are treated with bandage (therapeutic) lenses
Another use of contact lenses is to treat wounds on the corneal surface. The bandage called therapeutic contact lenses, ie therapeutic lenses, are used to cover the wound area in the cornea. This type of lenses are used for a short time, especially after the PRK method (Excimer Laser) or after cross-linking treatment. These types of contact lenses are also common in patients with dry eye disease.
Life is easier with contact lenses designed for special occasions!
Specially designed contact lenses are used in some special cases (very high or irregular astigmatism) and some corneal diseases (keratoconus). These examples include soft keratoconus lenses, hard gas permeable contact lenses, hybrid lenses (with both hard and soft materials) and scleral lenses. Thanks to these lenses, a much higher quality vision level can be presented to patients whose vision level and quality is low with glasses.
"Darkening lenses" against light sensitivity
In parallel with the advancement of technology, one of the lens types developed in recent years is the lenses that darken, that is, change color. These lenses give very successful results especially for people who are light sensitive, have difficulty driving at night, and are disturbed by the screen light. These lenses, which adjust the amount of light entering the eye continuously and rapidly, according to the intensity of the light in the indoor and outdoor environment, also protect the eyes from the harmful effects of UV by making high UV protection.
The progression of myopia is stopped with specially designed lenses that are worn at night.
Studies have shown that myopia has progressed especially in children in recent years. There are specially designed lenses called "Orthokeratology" that have evidence that they have stopped this progress and should be used at night. Patients wear this lens at night and take it off when they wake up in the morning. In the daytime, they continue their lives without lenses and glasses.
New trend: Daily disposable lenses
In daily disposable contact lenses, which are becoming a trend all over the world, a new lens is worn every day and the need for maintenance is eliminated. These lenses are especially recommended for people who work very intensely, do not want to deal with maintenance, prefer to wear lenses only on special occasions and do sports.
Use your contact lenses correctly, protect your eye health!
Correct use of contact lenses is of great importance. Because the wrong and bad use of lenses can lead to undesirable consequences that may even lead to vision loss. People who use contact lenses or want to use them should first be followed by an ophthalmologist. The use of lenses is generally recommended from the age of 12-13, who can self-care and have the awareness of providing personal hygiene.
What should we pay attention to when wearing contact lenses?
- The lenses used should be changed frequently, the wearing time of the lenses should not be exceeded,
- No lenses should be used during night sleep (except orthokeratology lenses) and should not be sleep while wearing lenses in the eye,
- Contact lenses and solutions should not be purchased from places of unknown origin (from the internet),
- Do not enter the pool or shower with lenses against the risk of infection,
- Contact lenses should not be contacted with any other solution or liquid other than the solution recommended by the doctor,
- When using lenses, eye redness, stinging sensation, burring or vision blurring, the lens should be removed immediately and consult a doctor.
- The lenses should not be contaminated with make-up material and should be worn before applying makeup,
- Glasses and contact lenses should be used alternately, glasses should be continued after 10-12 hours of lens use,
- Colored lenses used for cosmetic purposes should also be used under the supervision of a doctor in order not to cause any problems on the cornea or eye surface.
