Lens Crafting, Eliminating Cataracts

The general perception of cataracts is that it is a condition that predominantly affects middle-aged and elderly people. While certainly a great degree of older people does develop the condition, cataracts can advance in not only people who are more than 65 years old, but sometimes, younger women may also be at risk.

Dr. John Blaylock is an ophthalmologist and the chief surgeon, owner and medical director at the Valley Laser Eye Centre in Abbotsford, British Columbia. He concurred that people of all ages can be afflicted with the condition, and expanded on its sources.

“In our practice we see equal numbers of young women and young men,” Dr. Blaylock conveyed. “Cataracts can be seen in association with trauma, inherited disorders, metabolic disorders and certain medications. Ultra-violet exposure may increase the risk for cataracts in all age groups.”

A cataract is when an eye’s lens becomes blurry and therefore, significantly alters vision. The transparent area situated behind or inside your eye’s pupil is the lens, and it assists the retina (the light-sensitive tissue within the eye) in directing light and other impressions onto it.

In normally functioning eyes, light will traverse the lens to the retina; and once there, the light will be altered into nerve indicators, which are then directed towards the brain. Essentially, your eye’s lens must be completely transparent in order for the retina to obtain clear and distinct impressions.

However, with cataracts, the lens will be hazy and anything you see will be indistinct and foggy. Additionally, colours can fade, halos might emerge surrounding sources of light, glares can occur, as well as reduced vision at night, double vision and several images in either eye. Also, repeated prescription modifications for your contact lenses or glasses might be required.

Cataracts can be successfully remedied through lens replacement surgery, or refractive lens exchange (RLE). For example, cataract surgery is predominantly performed through phacoemulsification, also known as small incision cataract surgery. In this procedure, an eye surgeon will make a slight incision on the side of the eye’s cornea. A miniature probe, which discharges ultrasound rays, will then be placed in your eye, and the waves from the apparatus will fragment and diminish the lens, which can then be detached by suction.

In an extracapsular surgery, a lengthier incision will be made on the cornea’s side and the blurry portion of the lens will be extracted, while the remainder is separated through suction.

Nonetheless, your lenses will be supplanted with synthetic intraocular lenses (IOL), in which your eye’s lens is substituted with an artificial one, which is transparent and plastic. The procedure is shorter than an hour, and very little pain is experienced.

“IOL’s have revolutionized the quality of care and outcomes from cataract surgery,” Dr. Blaylock affirmed. “It allows us to correct nearsightedness, farsightedness, astigmatism and even reading vision.”

The different kinds of synthetic lenses include a standard, single focus IOL, which can cease future cataract formation, and various lifestyle lenses, which have additional benefits such as alleviating the need for glasses or contact lenses.

“Modern IOL’s rarely are associated with significant complications,” Dr. Blaylock maintained. “The benefits are that you can see without glasses or contacts with often 20/20 vision. The vast majority of people achieve one hundred per cent of their potential vision. The range of IOL selection now available allows us to treat almost all vision correction needs.”

Although, not everyone is suitable for IOL. These individuals might be afflicted with another eye condition or experience complications during the initial cataract surgery. In these instances, pliable contact lenses or glasses with an elevated magnification can be provided.

RLE surgery is associated with some risks, including infection, posterior capsule opacification (a thin and cloudy coating which can form on the rear of the artificial lens), augmented eye compression, and inflammation of the retina and cornea. The possibility of retinal detachment is somewhat enhanced post-surgery. An indicator of retinal detachment would include an abrupt escalation in small speck-like cobwebs, which appear in your field of vision. Your surgeon should examine you immediately if this occurs to avoid partial or complete loss of vision.

Post-surgery, patients will be advised to rest for a few hours before being driven home by someone else, and will be given synthetic tears and prescription eye drops to counter any irritation. Furthermore, patients should avoid any strenuous activity, swimming, bending over and rubbing their eyes for approximately two weeks.

If you have or suspect that you might be developing a cataract, consult immediately with a board certified and experienced ophthalmologist who has plentiful RLE surgical experience, and can ensure if you qualify for a lens replacement or require a different procedure. A qualified and caring ophthalmologist will safeguard your optical well-being and provide the best course of action for you.
