Our eyes are one of our most precious resources and taking care of them is vitally important as they have to serve us right from birth all through our earthly stay. Knowledge about eyes vision will help us gain a better understanding of the eye problems that occur and the corrective surgery that is available today, thanks to the enormous strides medical science has made. Read all about the various problems and solutions in this article.
Astigmatism is an optical defect whereby your vision is blurry because of the inability of the eye to bring an object into sharply focused image on the retina; irregular curvature of the cornea or lens causes this eyes vision problem. Astigmatic Keratotomy is a procedure that is performed to reduce the extent of astigmatism by reshaping your cornea from its original oval shape into a spherical shape. Anyone with a minimal or moderate degree of astigmatism who has had a stable prescription for a year at least and who does not have any serious vision problems can undergo this procedure to do away with the need for contacts or glasses.
INTACS is a procedure that is performed to reduce myopia and is an alternative to laser surgery. Tiny prescription inserts of plastic polymer are implanted in the outer edge of the cornea through surgery and they work by flattening the cornea to produce better focus and sharper vision. The advantages to this type of procedure are that the inserts can be removed; flexibility to make prescription changes when needed; no tissue removal and zero maintenance costs.
Lasik eye surgery has become over the years the most popular refractive laser surgery to correct eyes vision. A laser is used to change the cornea’s shape to correct the refractive error and the advantage to this system of correcting nearsightedness or farsightedness, even astigmatism is a permanent procedure.

As one of the most common outpatient vision correction procedures, Lasik surgery is a relatively straightforward process with the treatment itself taking only minutes. Los Angeles eye surgeons and surgeons in the world perform Lasik surgery on approximately one million eyes every year and it is no different than any other surgery
Laser Assisted in Situ Keratomileusis (Lasik) is intended to eliminate or reduce dependency on eyeglasses or contacts. Beverly Hills Lasik surgery has become more and more popular as the decades progress but still Laser Eye Surgery is not for everyone. Alternative surgery procedures like PRK and Lasik are excellent alternatives to glasses and contact lenses for patients suffering from myopia (nearsightedness), hyperopia (farsightedness), and astigmatism as well as a wide range of other vision conditions.
A procedure like this can permanently reshape the cornea, which is the clear covering of the front of the eye with the help of a laser. Most patients do not report any problems after the Los Angeles Lasik laser surgery. There are a wide variety of different optical lasers used in this procedure but common for all of them is that the laser will remove some tissue from the cornea.
Patients who have reached or are close to reaching the age of 40 should consider that their vision may be affected by conditions that cannot be treated with Lasik surgery, such as presbyopia. Patients with certain medical conditions or taking certain medications should not choose Lasik surgery because of the implication that it might give, according to top professional Beverly Hills Lasik surgeons. If you’re pregnant or nursing you will fall out of the ideal candidate classification and as it is advised to wait before considering laser vision correction. Patients with a condition called keratoconus are ineligible for the procedure and so are patients who have high levels of refractive error. Both parties are at a slightly higher risk for post-surgical astigmatism.
Laser vision correction surgery is an extraordinary procedure that has helped thousands of people see better and is an exciting opportunity for anyone who suffers from vision problems. Lasik surgery is the preferred vision correction surgery these days, despite its high cost. This type of surgery is however generally not the best option for older patients suffering from age-related conditions. Often these conditions can’t be treated with the Lasik procedure.

Cataract is the clouding of the lens of the eyes. It affects vision. A thin lining of cloudy natural lens is removed from the eye because it blocks the passage of light. This is how a cataract surgery is done. Cataract surgery is a harmless procedure. Every year, there are more than 1.6 Americans who undergo this treatment to repair their vision. More than half of the American population have cataract or may have been through a cataract surgery by the age of 80. Some people believe that when one eye has cataract, the other eye will definitely be next. This is a myth. Cataract doesn’t spread. It can occur in either or both eyes though.

On the day of the surgery itself, there is a list of things to do such skipping breakfast and avoiding intake of liquids. An eye drop to dilate pupils and sedative are given prior to the actual procedure. Topical anesthesia is also given in order for the patient not to feel the pain. After the areas around the eyes were completely cleansed and after a sterile covering is put into place, at least a small cut is done into the eye to enable the surgeon to remove the cloudy lens. There are two methods to remove the cloudy lens. One is through sonically breaking up the cataract then extracted out of the eye. The other one is through mechanically breaking up the cataract into small pieces then removed from the eye through a small incision. After this, a plastic or silicon intraocular lens will replace the natural lens that was taken off the eye.
After the operation, a protective shield is placed on the eye. Then the patient is usually sent home after few minutes in the recovery room. Surgeons advise patients to apply eye drops for a number of times in a day. This goes on for few weeks depending on the surgeon’s advice. Just like any other medical procedure, there are dos and don’ts patients are given to ensure effectiveness of the operation.
The price of a cataract surgery is around $3,000, exclusive of health insurance. Fortunately, HMOs, Medicare and other health insurances cover this specific surgery. It is indeed pricey however, the American Society of Cataract and Refractive Surgery reports 98% of the patients believe it is highly recommended since it simply worked for them.

Cataracts are a serious medical problem that will affect four out of ten adults over the age of 60, and almost 70% of adults over the age of 75. Cataracts, a clouding of the lens in the eye, can result in impaired vision and even blindness.
The PRELEX Procedure
One of the surgical procedures used to treat cataracts is Presbyopic Lens Exchange, or PRELEX. In this procedure, a small incision is made in the eye, the diseased lens is removed, and an artificial, intra-ocular lens (IOL) is replaced.
Why PRELEX for Cataracts?
Along with cataracts, many adults, as they age, begin suffering from what is known as presbyopia, a condition that prohibits the ability to focus on close objects. The advantages of the PRELEX procedure for cataracts are that the procedure can fix two problems with one procedure. Also, the PRELEX procedure has these added benefits:
- Elimination of any chance for future cataracts
- Procedure can be performed on patients’ with corneas too thin for LASIK
- Recovery of unaided distance vision
- Recovery of unaided near vision
Further, the PRELEX procedure, in fixing the cataract and the presbyopia conditions, can severely limit or fully eliminate the need for glasses or contact lenses.
The PRELEX Experts
Cataracts can be debilitating, but you do not have to live with them. Dr. Khanna and his team at the Khanna Institute of LASIK and Refractive Surgery are experts in performing the PRELEX procedure and can remove your cataracts while reducing or even eliminating your need for glasses or contacts.

We’ve all seen or at least heard of cosmetic makeover shows and witnessed the life-changing effects treatments can have on a patient’s life. With the development of technology and new minimally invasive procedures, cosmetic surgeries have become more advanced.
Laser eye procedures are one of the most frequently executed procedures on these makeover shows as they are quick, heal quickly and make a major difference to a person’s appearance. If you’ve been inspired by makeover shows and are considering a laser eye treatment, you will be glad to know that there are revolutionary techniques that can genuinely rid you of the need for any corrective eyewear. Imagine the bliss! No more glasses or fiddling with contact lenses, no more paying for visits to the optometrists or spending on contact lens solutions and broken frames!
The Advancement of Laser Eye Treatment
Many people are under still unaware that the effects of presbyopia (ageing eyes) can be so successfully corrected with laser eye treatment. This form of eye surgery is also a very useful option, especially for those who suffer from astigmatism. Other eye related problems including short-sightedness (myopia) and long-sightedness (hyperopia) can also be corrected through this type of ocular surgery.
This form of cosmetic surgery differs from mainstream aesthetic cosmetic surgery – the tummy tucks, the breast augmentations and the nose jobs – which have a vast impact on how the world sees you.
On the contrary, laser eye treatment has a very profound impact on the way you see the world. It is a wonderful gift to give yourself, one that will bring you joy during your every waking moment. Having freedom from corrective eyewear can be an incredibly liberating feeling and often, patients experience a heightened sense of self-esteem and confidence.
Are You a Suitable Candidate for Laser Eye Surgery?
If you suffer from short-sightedness, your eyeball is slightly longer and rounder than it should be. This means the light converges just in front of the retina, creating a blurred image at distance. In the past, this condition has been treated with glasses or contact lenses; however, it is also an ideal condition for laser eye treatment. By slightly reshaping the front of the cornea, the light is refocused precisely on the retina, eliminating short-sightedness.
In the case of people who suffer from long-sightedness, the eyeball is shorter and flatter than it needs to be, resulting in a blurred due to the light focusing on a point just behind the retina. Long-sightedness can affect both distance and near vision, but with laser eye treatment, this condition can too be eradicated, along with the need for glasses.
An astigmatic cornea is shaped more like a rugby ball than the normal sphere. People who suffer from astigmatism experience symptoms such as blurred small print, difficulty reading, inability to see both near and far without squinting, constant headaches and fatigue. Although it involves a slightly more complicated procedure than those associated with long and short sightedness, this condition can also be permanently treated with laser eye surgery.
Lastly, older candidates that suffer from presbyopia (ageing eye) will be glad to know that the effects of this condition can be countered with laser eye treatment. This allows most patients to reduce their dependency on reading glasses for many years.
The Laser Eye Treatment Process
The thought of laser eye treatment can seem daunting to those who don’t know much about it. That said, it is in fact a remarkably safe and potentially life altering procedure.
Just as you would conduct research on the plastic surgeon you’d want to operate on your body, a great deal of research should go into considering the right laser eye surgeon to operate on your delicate eyes. Once you’ve found a reputable surgeon who has deemed you a suitable laser eye candidate, you should establish a relationship of trust from the very first screening.
The procedure itself is minimally invasive – you will usually be given a topical anaesthetic so the surgery itself is virtually pain-free, you may experience slight discomfort, but that’s about it. Pre-laser eye treatment preparation for surgery on the day usually takes between 30 minutes to 1 hour. However, the operation itself takes only minutes, and the excimer laser used during the procedure is only active for mere seconds.
The WOW Effect
Laser eye treatment is one of the greatest alternatives to conventional corrective vision techniques. Within a considerably short amount of time you will be able to experience sharper vision, without the help of glasses and contacts. Headaches caused by eye strain will be eradicated and you will be left with a new perspective of the world.
Stop hiding behind glasses and consider undergoing a quick and transformative procedure – not an extreme makeover, but definitely transformative.
