What is a Cataract?

A cataract is an opacity or clouding of the eye’s natural lens (crystalline). It is still the leading cause of blindness in the world. The development of cataracts in adults is related to age, sun exposure, the use of snuff, poor nutrition, eye trauma and certain systemic diseases or the intake of certain medications to treat them.

The clouding of the natural lens of the eye may result in a blurred image. Cataract patients complain of blurred vision: distance, near or both. This can interfere with simple tasks such as driving or reading. Other common symptoms can be glare, halos of light and low brightness in color vision.

How is Cataract diagnosis done?

The diagnosis of a cataract can only be done through an eye examination, including visual acuity assessment, evaluation at the slit lamp and measuring intra-ocular pressure. If you are considered to be a candidate for cataract surgery, the ophthalmologist may also examine the back of the eye evaluating the retina and optic nerve. If a cataract is mature (extremely dense) or hypermature (white), he will use an ultrasound scan known as Scan B to rule out a retinal detachment and ocular tumors prior to proceeding with cataract surgery.

The progression of cataracts is highly variable, but they will undoubtedly worsen in severity. Changes in graduation on lenses or glasses can help improve vision as the cataract progresses, since most of cataract induce near vision problems (myopia). Despite this, for most patients the change of eyeglasses has a minimal impact on visual quality. Besides changing glasses, the other option for treating cataracts is surgery.

About Cataract Surgery

Currently, most cataract surgery is performed with microscopic size incisions, using advanced ultrasonic equipment to fragment the cataract into small pieces therefore allowing the insertion of the foldable intraocular lenses (IOL) while keeping the size of the small incision. Cataract surgery today is the result of at least 20 years of extraordinary advances in technology and surgical techniques, and allowing millions of people return to a clear and sharp vision. Cataract surgery can restore vision to levels you never thought possible.

Phacoemulsification and IOL (Intraocular Lens) insertion

Here are the main steps of cataract surgery using the micro-incision procedure, phacoemulsification (removal of the cataract by ultrasound), and the use of a foldable implantable lens. This procedure as described merely states the basic principles, surgeons may use variations as appropriate, depending on the type of cataract and the patient being treated.

The commonly used cataract incision is about 3 millimeters long. The careful construction of the incision and its minimum size allows it to be a “self-sealing type”, ie, in most patients this surgery can be performed virtually “no sutures.”

The surgeon then creates an opening in the anterior chamber of the lens, which created by a thin membrane surrounding the cataract. This procedure is called capsulorhexis and requires an extraordinary precision. This membrane is actually thinner than a red blood cell and the surgeon should remove it carefully in a space of only 3 mm in depth.

The removal of the lens with phacoemulsification is the phase of the surgery which uses ultrasonic vibrations to break the cataract into smaller pieces. These fragments are then removed from the eye using the same instrument. The posterior lens membrane is left intact to help support the intraocular lens (IOL) implant.

The intraocular lens is usually folded and passed through the small incision, then it opens to be implanted within the “capsular bag.” The lens has arm-like structures (known as haptic) that hold it centered in the capsular bag. The IOL does not usually require sutures to remain in good standing. Its position is the same as the eye’s natural lens (cataract) therefore very well tolerated and provides optimum visual results. At this time, the cataract surgery with IOL implantation is complete.

The advantage of this type of surgery is that the patient has less discomfort during and after surgery, and has a faster recovery of vision. The risks of cataract surgery are minimal, however, it is not totally risk-free because it is a surgery like, and any other, it may have some complications.
