An overview of “Monovision LASIK”

About Presbyopia & Loss of Accommodation

Individuals expecting LASIK eye surgery or at any other place per se by the age of 40 are likely experiencing a universal aging phenomenon; presbyopia. The condition is caused by loss of accommodation or inability of the lens to focus as we age.

Of the both, loss of accommodation is a hardening of the natural crystalline eye lens which compromises flexibility as it continues to expand over the lifetime. Once begins, an individual will find it extremely difficult to focus at near objects which definitely require reading glasses.

Preoperative consultation

Like any surgical procedure, monovision LASIK also require thorough examination and consultation of the eye doctor for overall health and aptness of the patient to undergo the procedure. In fact, there’ve been cases when patients had their refractive surgery and still require wearing eyeglasses or contact lenses. Counselling or consultation of the presbyopic patient would depend on the severity of the onset and the current state of refractive error.

The primary or first category of such patients fall under the banner of hyperopic or presbyopic as well as those suffering from astigmatism! Such individuals are already wearing eyeglasses or contacts. The second category of patients are myopic that can easily see and read nearby objects but require eyewear for distant vision. These individuals are unaware of losing even near vision post-surgery and often have difficulty in deciding on the procedure.

The third and final category includes patients who definitely require reading glasses and have the freedom to undergo monovision LASIK eye surgery in Dubai to rid them of any such eyewear. Only a single eye would require corrective treatment.

Adverse effects

Understanding the side-effects of monovision LASIK is crucial for both surgeon and patients alike that shouldn’t be ignored whatsoever. Remember that counter effects are a direct result of a possible imbalance or anisometropia caused by the monovision laser treatment itself.

Symptoms of the adverse reaction may include blurry or foggy vision, glare and halos, reduced night-time vision, compromised depth perception and even transient diplopia as a result of temporary strabismus. Side-effects tend to vary per the patient, depending on the severity and overall health contributing to vision.
