A cataract is a common condition that causes a clouding of the eye's natural lens, and affects millions of people each year, including more than half of all Americans over the age of 65. Cloudiness develops as a result of changes the quality of protein in the lens and causes a progressive, painless loss of vision. Some indications that a cataract may be forming are: Blurred or hazy vision, double vision, poor vision in bright light, seeing halos around lights, yellowish tinged vision, night vision difficulty.
Cataract surgery is a relatively painless procedure. It has a very high success rate and more than 99 percent of cataract surgery patients regain useful vision. It is a minimally invasive procedure that involves numbing the eyes with topical eye drops anesthetics and then making a tiny incision into which an ultrasonic probe is inserted. The probe breaks up, or emulsifies, the cloudy lens into tiny pieces and then suctions them out of the eye. Then an artificial clear lens (called an intraocular lens, or IOL) will be implanted in the eye. Surgery usually takes only a few minutes to perform. After the procedure, the eye will be patched with a clear sterile fenestrated shield to protect the eye from trauma and you will be asked to rest for a while. Patient can return home the same day, but will need someone to drive them home. For the next few days, you may experience itching, mild discomfort, fluid discharge and sensitivity to light and touch. Your doctor will prescribe eye drops to help the healing process and to reduce the risk of infection.
There are several different IOLs available to help each Beverly Hills patient achieve the best possible results from his/her cataract surgery. Multifocal IOLs allow for full vision correction at near, intermediate and far distances, completely eliminating the need for eyeglasses or contact lenses in most patients. Some IOLs such as Toric IOL can also correct astigmatism.
In the past, cataract surgery only involved monofocal lenses, which could only focus on objects near or far, but could not adjust to accommodate varying distances. These patients still had to rely on glasses or contact lenses after surgery in order to see clearly at all distances especially in older patients suffering from presbyopia.
Pseudoaccommodative or refractive lenses are another type of lenses that are able to correct distance and near vision.
Recently we have new technology called: LASER CATARACT SURGERY, which is a new approach to do cataract surgery with Femtosecond laser or Nanosecond laser, which is more precision and fast recovery. Once the cloudy lens has been removed, a new artificial lens is implanted into the eye. This lens is known as an intraocular lens (IOL), and can often be inserted through the same incision that the old lens was removed from.
Monofocal Aspheric IOL
As technology progresses, cataract surgery becomes more and more effective in its ability to restore vision as accurately and naturally as possible. There are many options for cataract patients as to which type of replacement lens they desire with surgery, but recent studies have shown that monofocal aspheric intraocular (IOL) lenses yield the most satisfied patients.
Aspheric lenses provide improved functional vision over traditional spherical lenses, which do not correct spherical aberration.
Although multifocal IOLs are available that let patients experience corrected distance and near vision with no further need for glasses, monofocal lenses are still used commonly by those, who do not mind wearing reading glasses.
No intraocular lens comes without disadvantages, so it is ultimately up to each patient to decide which lens would most benefit his/her life.
Intraoperative Floppy Iris Syndrome (IFIS)
Patients who take tamsulosin (Flomax or similar medications), which is called alpha1a-adrenergic antagonists for the treatment of benign prostatic hypertrophy (BPH), develop changes in their texture of their iris named Floppy Iris Syndrome, causes poor dilation and very loose iris. This condition is dangerous for the cataract surgery because this kind of irises are prone to develop progressive intraoperative constriction and iris prolapse out of the eye which increases the rate of cataract surgery complications in this condition. That is why always patients with poor pupillary dilation should be questioned about the use of Flomax and similar medications. Even though after cessation of the medication for long time still we can see the effect of the medication on the iris, therefore we shouldn’t ask patients to stop the medication before surgery.
Capsular Opacification and Second Cataract and YAG Caspsulotomy
During cataract surgery, your Beverly Hills doctor replaces the clouded, blurry area of the lens with an artificial one to correct vision. However, after surgery, many people experience a gradual clouding on the covering of the new lens, a condition known as after cataract or secondary membrane or secondary cataract. Clouding is the most common complication of cataract surgery and can cause blurred vision to return, but a solution is available to treat this side effect.
A procedure called a posterior capsulotomy, using an Nd: YAG laser, can be performed to remove the back lining of the lens capsule and let light pass through to the retina. The capsulotomy can be performed in your doctor's office and is a painless procedure that does not require any anesthesia. It is considered a safe procedure, which takes 2-3 minutes to be performed in the office. Most people experience improved vision and reduced glare after undergoing a posterior capsulotomy.
