The shape of a healthy cornea is dome-like. When there is an alteration to this shape, it may lead to nearsightedness, farsightedness or astigmatism, and cause a loss of vision. However, there are several other types of eye impairments that may lead to the loss of sight.
But irrespective of the factors that cause a loss of vision, there are also several ways to improve the eyesight and clarity of the image an individual sees. The most significant ways of improving one’s eyesight and image clarity include
– The use of a contact lens
– Opting for LASIK surgeries
– The use of implantable lens
– Cataract surgery
Contact lenses are round, transparent disks placed on the surface of the eyes to enhance vision for those suffering from an eye defect temporarily.
Contact lens is specific in function to several causes of vision loss. These lenses may either be a concave or convex lens for converging or diverging the rays of light from an object that enters the eyes on the retina. Converging lenses and diverging lenses are used to correct nearsightedness and farsightedness, respectively.
You can purchase a contact lens at an affordable price of about $30 per box; however, this box comprises three to four contact pairs. The affordability of this vision solution makes people get any type of contact even when they are mostly ignorant of the cause and severity of their eye defects, and this may deteriorate the vision loss rather than enhancing it.
Therefore it is always advisable to visit a doctor who is well vast in the knowledge of eye defects to prescribe the type of contact fit to enhance your vision.
LASIK is an acronym for Laser In-situ Keratomileusis. It is a Laser eye surgery that involves the reshaping of the cornea that results in the permanent enhancement of vision.
LASIK surgical procedures involve the use of a computer-guided laser for effectiveness, accuracy, and safety. Your ophthalmologist will need to create a detailed map of your cornea to fathom the method of reshaping your cornea because it is different in all individuals.
The ophthalmologist will then make use of a precision instrument to remove a small portion of the corneal tissue that makes the cornea out of shape and reshape them with a computer-guided laser. LASIK surgical procedures are fast, with a short duration of not more than thirty minutes for the completion of both eyes.
Although this type of eye defects treatment procedure comes with an almost immediate improvement of vision after surgery, they also have a few disadvantages.
The most significant disadvantage is the occurrence of a few side effects during the healing phase of the surgery, such as Itchy eyes, dry eyes and extreme sensitivity to light. However, these side effects gradually mitigate until they are no more as your eyesight becomes stable.
The use of implantable lenses is the best alternative for vision loss because of the degree of vision enhancement it comes with. There are two different types of implantable lenses based on they are positioned on the iris, either on or behind the iris. The types of implantable lenses are verisyse and visian intraocular lenses.
Verisyse lenses are placed directly on the iris, while visian intraocular lenses are placed behind the iris via a surgical procedure. If you opt for an implantable lens treatment procedure for your vision loss, it comes with the advantage of high-quality vision clarity over the use of removable contact lenses. But they also bring about a disadvantage of side effects such as irritation and pain after the procedure is complete.
An ophthalmologist will test and examine the type and severity of your eye before recommending the type of implantable lenses apt to improve your vision’s clarity. However, this incredible, life-changing benefit comes at a very high price.
The unaffordable characteristic of this treatment procedure is further made inconvenient to individuals because it is elective surgery. You will have to pay about $3,000 to $5,000 without any assistance from health insurance.
A Cataract is primarily the clouding of your lens that usually focuses the ray of light entering your eyes on the retina to give a clear image. Therefore, the cloudiness of the image formed because of the Cataract can be corrected by replacing the principal source, the lens.
In this surgical procedure, the ophthalmologist will first numb your eyes from pain with the use of certain eye drops before effectively and cautiously completing this surgery with the help of laser-assisted technology or ultrasound energy.
Cataract surgery offers incredible benefits of better eyesight to those with a high degree of severity but not individuals with existing eye damage—a few side effects such as distorted vision, Posterior capsule opacification, and temporary bleeding.
The cost of treating your cataract via cataract surgery is partially or totally covered by insurance. But you will have to pay an expensive cost of about $3,600 to $6,000 for cataract surgery if you are not insured.
However, the most significant factor that influences this cost is the type of intraocular lens your eyes require. It depends on your ophthalmologist’s recommendation, but the intraocular lens may be an aspheric lens, multifocal lens, toric lens or accommodating lens.
The improvement of an individual vision may involve using a vision-enhancing instrument (such as a contact lens or glasses) or surgical procedures. The type of treatment procedure you will need depends on the type and severity of your eye defect.
Hence, it is always advisable to visit an ophthalmologist to examine your eye condition and recommend the best treatment procedure to improve your vision permanently.
