Lenses for glaucoma in adults

Glau­co­ma is a very seri­ous eye dis­ease that, if not treat­ed, can lead to com­plete blind­ness in one or both eyes. But is it pos­si­ble to wear con­tact lens­es with this pathol­o­gy, will they harm?

An oph­thal­mol­o­gist will help you choose lens­es for glau­co­ma after a com­plete exam­i­na­tion. Pho­to: Shut­ter­stock

Glau­co­ma affects the optic nerve, which receives sig­nals from the reti­na, process­es them, and trans­mits them to the visu­al cor­tex of the brain. With­out treat­ment, the nerve fibers die, and it will be impos­si­ble to restore vision.

The key prob­lem in glau­co­ma is the accu­mu­la­tion of excess intraoc­u­lar flu­id, which has an obstruct­ed out­flow path. Against the back­ground of flu­id accu­mu­la­tion, intraoc­u­lar pres­sure ris­es, which leads to clamp­ing of the optic nerve, its grad­ual destruc­tion. If the process is not stopped, it will lead to blind­ness, which then can­not be elim­i­nat­ed.

Although opti­cal cor­rec­tion is one of the treat­ments for glau­co­ma, it is used only in com­bi­na­tion with oth­er ther­a­pies. The entire course is indi­vid­u­al­ly select­ed by the doc­tor, the main goal is to reduce the load on vision, restore its clar­i­ty and improve the qual­i­ty of life. But can con­tact lens­es be used to cor­rect refrac­tive errors?

Can I wear contact lenses for glaucoma?

Cor­rec­tion with glass­es is not suit­able for all patients. This is due to lifestyle, active sports or pro­fes­sion fea­tures. There­fore, lens cor­rec­tion is con­sid­ered a more con­ve­nient option for cor­rect­ing refrac­tive errors. But a nat­ur­al ques­tion aris­es, is it per­mis­si­ble to wear con­tact lens­es for glau­co­ma in order to cor­rect refrac­tive errors?

The answer to this ques­tion will be giv­en only by an oph­thal­mol­o­gist, tak­ing into account a num­ber of fac­tors that will be clar­i­fied after a detailed and com­plete exam­i­na­tion. In gen­er­al, wear­ing con­tact lens­es is not pro­hib­it­ed in the pres­ence of glau­co­ma, but it is nec­es­sary to select such mod­els that will car­ry oxy­gen well to the cornea, can pro­vide a suf­fi­cient lev­el of mois­ture and will not dis­rupt the nutri­tion of the eye struc­tures.

Glau­co­ma in adults: how is it diag­nosed and treat­ed today

But often the mate­r­i­al of con­tact lens­es does not inter­act well with some drops for glau­co­ma, which a doc­tor can pre­scribe to cor­rect the pathol­o­gy. Some solu­tions for the treat­ment of glau­co­ma can affect the trans­paren­cy of the lens, its phys­i­cal char­ac­ter­is­tics, so you can not use drops dur­ing the peri­od of wear­ing prod­ucts.

If you need to choose opti­cal means of con­tact cor­rec­tion that will improve vision in glau­co­ma, but at the same time they will not harm the eyes, you need to con­tact an oph­thal­mol­o­gist.

Which lenses are best for glaucoma

Due to the increase in intraoc­u­lar pres­sure, visu­al acu­ity suf­fers, the size of the visu­al fields decreas­es. Basi­cal­ly, prob­lems begin after 40 years, at a young age, pathol­o­gy is less com­mon. With­out treat­ment, it pro­gress­es, and patients with glau­co­ma see much worse than those who suf­fer from near­sight­ed­ness or far­sight­ed­ness. And accord­ing­ly, they need a full-fledged cor­rec­tion of visu­al dis­or­ders. The sever­i­ty of visu­al impair­ment is large­ly deter­mined by the degree of dam­age to the optic nerve, since it is he who trans­mits sig­nals from the reti­na to the brain.

Con­tact lens­es, if cho­sen togeth­er with a doc­tor, can solve some of the prob­lems of refrac­tion, improve visu­al acu­ity and reduce eye strain. You can use both soft lens­es, which are com­fort­able to wear, and hard, per­me­able to gas­es, but an expe­ri­enced oph­thal­mol­o­gist at the appoint­ment can choose the type of prod­uct.

He will deter­mine the sever­i­ty of refrac­tive error, assess the con­di­tion of the eye tis­sues and select spe­cif­ic mod­els.

What is the difference between lenses for glaucoma and ordinary lenses?

In gen­er­al, almost all types of lens­es are suit­able, the prod­ucts have no fea­tures specif­i­cal­ly for this pathol­o­gy. It is only impor­tant to deter­mine in advance which of the drugs should be used in the ini­tial stage of the dis­ease. Some of them are incom­pat­i­ble with wear­ing lens­es, can accu­mu­late on their sur­face, and lead to prod­uct intol­er­ance.

In addi­tion, dur­ing the peri­od when you need to take drops in a course, it is rec­om­mend­ed to remove the lens­es so that the drugs fall exact­ly on the mucous mem­branes of the eye­ball.

On a note

How to choose good biweek­ly con­tact lens­es

Reviews of doctors about lenses for glaucoma

“While wear­ing lens­es,” says oph­thal­mol­o­gist Natalia Bosha– in patients with glau­co­ma, 2 main para­me­ters must be observed:

    use only lenses selected by an ophthalmologist (the radius of curvature of the lenses is important — if they sit too tightly on the cornea, the outflow of fluid from the anterior parts of the eye may be disturbed, which aggravates the course of glaucoma),
    drops that are prescribed for glaucoma must be instilled half an hour before putting on the lenses, or after removing the lenses.

Sub­ject to these rules, peo­ple with glau­co­ma suc­cess­ful­ly use con­tact lens­es.

Can lenses provoke glaucoma or its complications, progression of the disease?

Maybe with the wrong lens­es. When choos­ing optics, the radius of cur­va­ture of the lens­es is impor­tant — if they sit too tight­ly on the cornea, the out­flow of flu­id from the ante­ri­or parts of the eye may be dis­turbed, which aggra­vates the course of glau­co­ma.

When are contact lenses contraindicated for glaucoma?

In the absence of intraoc­u­lar pres­sure com­pen­sa­tion.

Can I wear colored lenses for glaucoma?

Col­ored lens­es quite often have an aver­age cur­va­ture, which leads to dif­fi­cul­ties in indi­vid­ual selec­tion. If you man­age to find col­ored lens­es that fit the size of this per­son, you can also wear them with glau­co­ma.
