What is mean by having a Refractive Error in the Eye? How it is Corrected?

refractive error treatment

A refractive error is a very common eye disorder which affects your eye ability to focus on the images from the outside world which means you will face difficulty to see the objects clearly. The result of refractive errors is blurred vision and sometimes this is so severe that it will cause visual impairment.

What causes refractive error eyes?

The following are the four most common causes of refractive errors:

a) Myopia (nearsightedness): In this type of refractive error you will face difficulty in seeing distant objects clearly. To correct the condition of myopia your surgeon will suggest you use a concave (-) lens. Myopia refractive error in children will frequently increase until the child stops growing.

b) Hyperopia (farsightedness): In this type of refractive error you will face difficulty in seeing close objects clearly. Hyperopia is a refractive error in which adults see the blurred objects both near and distant. However, children and young adults dealing with mild hyperopia may be able to see the objects clearly because of their ability to accommodate. To correct the condition of hyperopia your surgeon will suggest you use a concave (+) lens.

c) Astigmatism: This is a type of refractive error in which you have distorted vision which results from an irregularly curved cornea and the clear covering of the eyeball. When your surgeon tries to correct astigmatism with eyeglasses, a difference in image size is produced and it can lead to difficulties with the fusion of two different sized images.

d) Presbyopia: In this type of refractive error you will face difficulty in reading or seeing at arm’s length objects, but this type of refractive error usually linked to aging and it occurs almost universally. To correct the condition of presbyopia your surgeon will suggest you use a concave (+) lens so that you can view the near objects.

It has been found that the refractive errors cannot be prevented; however, refractive errors can be diagnosed by an eye examination and it will be treated with contact lenses, corrective glasses or the best and the last option refractive surgery. The eye surgeon will provide the correction of the refractive error eye in different forms which depend on the eye defect, the age of the person and your requirement in terms of your work or activity performed.

According to the survey conducted by the representative of We Care India, there are nearly half of the population across the globe live with visual impairment due to uncorrected refractive errors and this population does not include the people living with uncorrected presbyopia, which is quite significant.

What are the symptoms of refractive error eyes?

The symptom of refractive errors which is noticed first is the blurred vision for distant objects, near objects, or both. It has been found that sometimes the excessive ciliary muscle tone can also cause headaches. Squinting for a long time and frowning with ocular use can also lead to headaches. The study says that excessive staring can lead to eye irritation, redness, itching, visual fatigue, foreign body sensation, etc. Frowning when reading and blinking or rubbing of the eyes in excess are symptoms of refractive error in children.

How the surgeons will treat refractive error eyes?

The surgeons at the hospitals under We Care India will correct refractive error eyes with eyeglasses, contact lenses, or refractive surgery.

a) Eyeglasses: This is one of the simplest and safest ways to correct refractive errors. Your eye surgeon will prescribe appropriate lenses to correct your refractive error which gives you optimal vision.

b) Contact Lenses: They are a safe and effective option if fitted and used properly. Your eye surgeon will advise you to wash your hands and clean your lenses to reduce the risk of infection. According to the study, contact lenses have provided clearer vision, a wider field of vision, and greater comfort to many people.

c) Refractive Surgery: Your surgeon will perform the surgery to change the shape of your cornea permanently. This change in the shape of your eyes will restore the focusing power of your eye by allowing the light rays to focus precisely on your retina for improved vision. At the hospitals under We Care India, we have many types of refractive surgeries which will be discussed with you after the surgeon will examine your eye condition and then he/she will tell you which surgery is the best to correct your refractive error eyes.

Surgery for Refractive error eyes

When non-surgical treatments fail to provide successful results, the only option left to treat the refractive errors nearsightedness, farsightedness, and astigmatism is surgery. Refractive surgery is of two types which are:

a) LASIK (Laser in situ keratomileuses): LASIK is a refractive surgery which is performed to correct nearsightedness, farsightedness, and astigmatism. In LASIK procedure your eye surgeon will create a very thin flap in the central part of the cornea with a laser. The flap is lifted, and computer-controlled pulses of highly focused ultraviolet light from an excimer laser to reshape the cornea and after that, the flap is laid back in place and will heal over several days.

b) PRK (Photorefractive keratectomy): PRK is a refractive procedure which is used to correct nearsightedness, astigmatism, and farsightedness. This procedure requires the use of excimer laser to reshape the cornea and no flap is created as in LASIK. At the beginning of the procedure, the cells on the surface of the cornea will be removed. After the surgery, your surgeon will place the contact lens on the eye which acts as a bandage. This will help the surface cells to grow back and relieve pain.

How much is the Refractive Errors Treatment Cost in India?

The Refractive Errors Treatment Cost in India is very reasonable which ranges from USD 3,000 to USD 5,000 depending on the procedure and this cost can be easily afforded by each individual. If you compare the cost of refractive error treatment in India with other developed countries then you find India is the most reasonable place as this treatment will cost you around USD 15,000 in the countries like the USA.
