Treatments for Nearsightedness and Farsightedness

your next step may be to undergo laser eye surgery

Myopia, or nearsightedness, is a very common vision disorder that often makes focusing at close objects difficult. However, objects that are nearby will be just as clear as those that are far away. Those who suffer from myopia have to wear corrective lenses, either custom-fitted or over-the-counter, or opt for laser eye surgery. The best way to treat nearsightedness is through the use of corrective lenses. If these don’t work for you, then your next step may be to undergo laser eye surgery.

There are three main factors which determine the severity of nearsightedness: eye muscle strength, the age of the person, and whether the disorder is hereditary or not. When the eyes are not perfectly aligned, it causes difficulties seeing objects far away.

The following are some common symptoms of myopia:

 

Hyperopia or farsightedness is similar to nearsightedness in that it causes difficulty seeing objects close by. But hyperopia also affects objects that are further away. This type of nearsightedness can either be astigmatism or osteolysis. This condition causes blurred images on reading as well as nearsightedness on the retina. It is harder to fix than hyperopia.

Phakic IOLs (or, “photic lenses”) are special lenses made for nearsightedness. They are available in two basic designs: soft lenses or rigid gas permeable lenses. Soft lenses are more comfortable and easier to wear. Rigid gas permeable lenses are more durable and provide better vision quality. Different parts of the eye must be cleaned with an Ophthalmologist’s solution, but once this is done, the eye stays hydrated. However, these lenses are less comfortable than soft lenses and may cause irritation and dryness of the conjunctiva, eyelids and occasionally the cornea.

Corrective Lenses For Presbyopia Corrective Lenses correct the eye for nearsightedness by straightening the cornea, restoring normal vision. It is usually recommended for older children and adults whose eyes have gradually become less able to focus light. Lenses are suitable for nearsightedness if your eye doctor finds your eye focusing light from far away. Presbyopia can happen if you wear contact lenses for a very long time.

Dichroic IOLs (“dichroic” means “of two” and “refractive errors” means “refractive error”) are a new class of nearsightedness treatments. Unlike traditional myopia correction surgeries, Dichroic IOLs correct both nearsightedness and farsightedness. The IOLs, which are custom-made for each patient’s eye, include two separate lenses that, when placed together, form a “virtual lens” which corrects both aberrations.
