Cataract (Clouding of the Lens) Eye Treatment in Israel

What is a Cataract?

A cataract is a clouding of the lens inside the eye, which leads to a decrease in vision. A normal lens is clear. It lets light pass to the retina, the light-sensitive tissue at the back of the eye. As a cataract develops, it becomes harder for a person to see. Vision may become cloudy or blurry, and colors may fade. It is the most common cause of blindness and is conventionally treated with surgery. Therefore, it makes sense to undergo the cataract surgery when vision loss interferes with everyday activities such as driving, reading, or watching TV, and so on. Also, it is not recommended to wait until the eye will turn blind, as in this case the surgery could be more difficult.

Cataract Causes

  • Age-related cataract (in most cases)
  • Congenital cataract (childhood cataract)
  • Secondary cataract (as a result of other medical conditions, like diabetes, or exposure to toxic substances, certain drugs like steroids)
  • Traumatic cataract (forms after injury to the eye)

Cataract Symptoms

  • Vision that is cloudy, blurry, foggy, or filmy
  • Changes in the way a patient sees color because the discolored lens acts as a filter
  • Sudden changes in glasses prescription
  • Progressive nearsightedness as a patient may no longer need reading glasses
  • Vision is sometimes worse when light is very bright (glare)
  • Problems driving at night such as glare from oncoming headlight
  • In some rare cases patient may have intraocular inflammation
  • Vision may be affected by small spots or dots

What can I do if I lost some vision from cataract?

As a matter of fact, there is no proven prevention or medical treatment for a cataract, including the eye drops and exercises. Surgical removal of the cataract remains the only effective treatment available to restore vision. It makes sense to undergo the cataract surgery when vision loss interferes with everyday activities such as driving, reading, or watching TV, and so on. The cloudy lens is removed from the eye and an artificial clear plastic one is put in its place that is selected for each patient individually. Cataract surgery is the most common in the world. In 98 percent of cases, people who have cataract surgery have better vision afterwards.

The Day of Surgery

A patient should arrive 30 minutes before the appointment time at the Medical Center for the surgery. Also, a patient should bring the proper payment obligation and all prescription medications that should be taken as usual, except for those that are prohibited before the surgery, such as aspirin and anticoagulants (blood-thinning drugs). In addition to that a patient must notify Prof. Igor Kaiserman on receiving anticoagulants. Before the surgery, a patient will be informed in details about the surgical procedure. Next, the patient must sign a consent form. In addition to that mydriatic drug will be instilled into eyes of the patient. Finally, the patient should take a shower or bath before the surgery to reduce the risk of infection.

Types of Anesthesia

This surgery is usually performed under a local anesthesia. In this case, a patient must avoid food or beverages at least 3 hours before the operation. The local anesthesia is done by instillation of anesthetic or injection near the eye.

Surgery Process and Types of Artificial Lenses

  • Monofocal lens - this is a fixed-strength lens which is set for one level of vision - usually distance vision.
  • Multifocal lens - this type of lens may have two or more different strengths; near and distance vision.
  • Artificial lenses to correct astigmatism (toric lenses). Astigmatism (or cylinder) is a vision condition that causes blurred vision due either to the irregular shape of the cornea, the clear front cover of the eye, or sometimes the curvature of the lens inside the eye. An irregular shaped cornea or lens prevents light from focusing properly on the retina, the light sensitive surface at the back of the eye. As a result, vision becomes blurred at any distance. As for a patient who has astigmatism and had a standard “monofocal or multifocal” lens implanted, and the patient will still need to wear glasses with cylinder correction. In this case, it is recommended to implant the toric lens that will be capable at the same time to correct astigmatism as well.
  • Multifocal toric lenses for near and distance vision are able to correct astigmatism (cylinder).

It should be noted that for the multifocal and cylindrical lenses are additional fee. For the most part, the stitches are often not needed to close the surgical incision, but some incisions may need very thin stitches. The whole procedure should not take more than about 30 minutes.

Cataract Laser Surgery

In traditional cataract surgery, the eye surgeon uses a hand-held metal or diamond blade to create an incision in the area where the sclera meets the cornea. The goal in creating this incision is to go a partial depth vertically, then go horizontally in the cornea and then enter into the eye. Then the surgeon can break up and remove the cataract, which is located right behind the pupil. Next a lens is inserted and implanted, to replace the cloudy natural lens. Today, there is new laser approach to cataract surgery. There is available "Alcon" laser device manufactured by the American company based on LenSx Laser technology. The laser is utilized to make the corneal incisions, reduce or control the astigmatism, create a circular opening in the anterior capsule of the cataract and fragment the cataract.
This technique significantly reduces the duration of the surgery and provides higher accuracy and safety compared to the traditional cataract surgery. Studies have shown that cataract surgery can help patients to regain what they have lost, both in terms of vision and the quality of life. Now, a technological breakthrough is available for use in cataract surgery.

Benefits of Cataract Laser Surgery

  • Provide greater precision in creating openings in the cornea and lens
  • Cataract surgery is safe and easy, and usually it is that way
  • This surgical procedure allows recovering in less time and with fewer complications
  • For the first time, there is possibility to combine in one cataract surgery the correction of refraction and correction of astigmatism
  • This procedure to crush lens can greatly reduce the risk of damage to the corneal endothelium and lower the incidence of postoperative corneal edema
  • This procedure has a smaller percentage of complications in cases of complicated cataract surgery

It should be noted that in the case of cataract laser surgery may be charged an additional fee.

Post-Surgery Care

After the surgery a patient will wear an eye pad for protection for a short while. The eye pad will remain until the doctor’s checkup for the next day. Also, a patient may wear the glasses. It is forbidden to rub or press on the eye.
Pain therapy: A patient should take painkillers in case of the pain in accordance with the doctor’s recommendations. If medication does not relieve the pain within half an hour after taking it, a patient should notify Prof. Igor Kaiserman. Sometimes, the pain is a sign of increased intraocular pressure, which may require urgent treatment.
Mobility: A patient is free to move around and get out of bed.
Food: A patient should eat and drink as usual.
Bath and shower: A patient may take a shower, but should not wet the eye during the first post-surgery days.
Medication therapy: A patient should continue to take medication, including eye drops as prescribed by a doctor.
The duration of post-surgery hospital stay: A patient will most likely go home after a few hours (in some cases the eye doctor’s permission may be required).
Post-surgery vision: A healthy eye has higher chances for good vision, as people who have cataract surgery have better vision afterward. Final eyeglass prescription will be given for at least 4 weeks after the surgery.

There are possible some post-surgery complications

  • Loss or reduction in corneal transparency
  • Bleeding or swelling in the retina and retinal detachment
  • Infection, it is a rare but serious complication that requires immediate diagnosis and treatment.

Most of the above complications are treatable. In most cases, the cataract surgery is very successful in restoring vision.
