A cataract is a condition where the lens of the eye becomes cloudy or blurry. The vision becomes hazy, darker, and less colourful. A person may also experience vision loss/ total blindness. Cataracts can also be caused by trauma to your eye or diabetes.
Globally, nearly 18 million people suffer from cataracts. It is also known as the world’s single most important cause of blindness. Cataracts are usually caused by ageing and may become more common around the age of 50. Not just Old people babies and children get cataracts too. Cataracts grow in the eye’s lens, which focuses light to create the pictures we see. Lenses are normally clear, but cataracts make them hazy.
What Causes Cataract?
There are many causes of cataract. Some of the causes are mentioned below:
AGE: Getting a cataract while ageing is common for people this is called age-related cataract or senile cataract. It usually starts at the age of 40 and gradually the opacity of the lens increases to be clinically significant and reduce the vision. It is one of the most common of cataracts causes.
Inheritance: Genetics plays an important role as cataracts run in families especially the type of cataract called blue-dots cataract. Systemic diseases like diabetes mellitus hypertension too cause cataract. While hyperlipidemia and other diseases also cause cataract in younger age or accelerate its course to be clinically significant.
Lifestyle: Nutritional causes in which it can be caused by heavy alcohol consumption which is called alcoholism cataract, smoking or malnutrition with low levels of certain factors called antioxidants like vitamin C, vitamin E and carotenoids too play an important role in getting cataracts. Sometimes it can also occur after eye surgeries like retinal surgeries, glaucoma surgeries, and even laser surgeries.
Initially: Surgery for cataracts is without a doubt beneficial. During surgery, cataracts are removed and the eye’s lens is replaced by inserting an artificial one into the eye, or by wearing contact lenses or glasses. Unfortunately, artificial lenses cannot focus as well as natural ones, meaning children can still face a life of restricted vision even if they undergo surgery.
Individual condition: People suffering from refractive error, such as nearsightedness (myopia), farsightedness (hyperopia), astigmatism or presbyopia, refractive surgery is a method for correcting or improving your vision. There are various surgical procedures for correcting or adjusting an eye’s focusing ability by reshaping the cornea, or clear, round dome at the front of your eye.
Types of surgery: Some procedures involve implanting a lens inside your eye. The most widely performed type of refractive surgery is LASIK, where a laser is used to reshape the cornea.
- For people who are nearsighted, certain refractive surgery techniques will reduce the curvature of a cornea that is too steep so that the eye’s focusing power is lessened. Images that are focused in front of the retina, due to a longer eye or steep corneal curve, are moved closer to or directly onto the retina following surgery.
- Farsighted people will have refractive surgery procedures that achieve a steeper cornea to increase the eye’s focusing power. Images that are focused beyond the retina, due to a short eye or flat cornea, will be pulled closer to or directly onto the retina after surgery.
Astigmatism can be corrected with refractive surgery techniques that selectively reshape portions of an irregular cornea to make it smooth and symmetrical. The result is that images focus clearly on the retina rather than being distorted due to light scattering through an irregularly shaped cornea.
Refractive surgery might be a good option for someone with the following
- Want to be independent of glasses or contact lenses;
- Are free of eye disease;
- Accept the inherent risks and potential side effects of the procedure involved.
- Understand that you could still need glasses or contacts after the procedure to achieve your best vision
- Have an appropriate refractive error.
There is no globally-accepted, best method for correcting refractive errors. The best option should be decided after a thorough examination and discussion with an ophthalmologist.
Laser Cataract Surgery System
A number of medical device companies offer laser systems for performing laser cataract surgery. Systems that have attained all required medical agencies like FDA approval and are currently available for laser-assisted cataract surgery performed in the United States and rest of the world include:
This LenSx femtosecond laser system has laser data entry at left, a joystick control and an OCT screen at right, which offers the surgeon all-important guidance during laser-assisted cataract procedures.
- LenSx. The LenSx system was the first femtosecond laser system to gain FDA approval for cataract surgery performed in the U.S. The LenSx system is approved for corneal incisions, capsulotomies, and lens (cataract) fragmentation and has been used in more than 400,000 cataract refractive procedures worldwide.
- LensAR: The LensAR Laser System (LensAR, Inc.) is approved for corneal incisions, capsulotomies, and lens (cataract) fragmentation. The “AR” stands for “Augmented Reality,” which refers to proprietary imaging technology that collects an unprecedented spectrum of biometric data and then reconstructs a sophisticated 3-D model of the anatomy of each patient’s eye.
- Catalyst: The Catalyst Precision Laser System also is FDA-approved for the three primary steps prior to IOL insertion in laser cataract surgery (corneal incision, capsulotomy, and lens fragmentation). The Catalyst system also features a liquid optics interface that provides gentle docking of the laser to the eye, reducing risks associated with high eye pressure during laser cataract surgery, according to AMO.
- Victus: The Victus Femtosecond Laser Platform (Bausch + Lomb) also is FDA-approved for corneal incisions, capsulotomy and lens fragmentation in laser cataract surgery. The Victus system features proprietary Advanced Docking Technology that minimizes the possibility of eye tilt or distortion and enables precise alignment designed to maintain the natural shape of the eye during laser-assisted cataract surgery.
- Femto LDV Z8: This femtosecond laser system, produced by Ziemer Ophthalmics, offers a number of distinct advantages according to the company, including a higher repetition rate of the laser beam for faster procedures, low energy per laser pulse for gentler treatments, and overlapping laser spots for high precision and predictability.
All FDA-approved laser systems for laser cataract surgery have shown excellent outcomes in clinical trials. Typically, the skill of the surgeon is more important than the brand of laser used for the laser-assisted steps of your cataract procedure hence the patient can rely on the treatment stress-free.
Cost of Laser Cataract Surgery
Refractive laser-assisted cataract surgery costs more than conventional options around Rs.30000 to 60000 even more or less depending place to place. Extra costs associated with laser cataract surgery are unlikely to be covered private health insurance. Fees vary from one cataract surgeon to another, but it is likely you would pay a few thousand extra per eye out-of-pocket for a laser-assisted procedure.
Cataract surgeons use lasers due to their advantages which are evident when it comes to high-tech, premium implants such as presbyopia-correcting multifocal IOLs and accommodating IOLs.
Traditional cataract surgery is very effective and successful. People who do not want to invest out-of-pocket money in laser cataract surgery can still feel confident about the traditional approach. Laser cataract surgery is more appealing. With Laser more accurate incision, capsulotomy, and astigmatic correction may help patients achieve a goal of less dependence on glasses after cataract surgery.
