Cataract Surgery

Cataract surgery

In ancient times, the term “cataract” was used to describe this condition due to the whitening of the pupil. Cataracts entail the clouding of the eye’s lens, resulting in visual impairment and diminished vision. The causes of this condition may include factors such as aging (the most prevalent form of cataract), genetic predisposition, trauma, congenital factors, smoking, diabetes, and exposure to ultraviolet rays. Symptoms of cataracts encompass vision blurriness or deterioration, heightened sensitivity to light, reduced or faded perception of colors, and occasional double vision. While in the early stages, vision issues arising from cataracts can often be mitigated with the use of corrective lenses, advanced stages may necessitate surgical intervention to restore optimal vision. Presently, cataract surgery stands as one of the most commonplace and highly successful surgical procedures, typically conducted under local anesthesia. However, cataract surgery is a procedure to remove the lens of the eye and, in most cases, replace it with an artificial lens.

The progression of cataracts varies from person to person, and individuals aged 50 and above can effectively manage it on time under the guidance of an ophthalmologist. Without timely intervention, a small subset of patients may experience an elevation in intraocular pressure, potentially leading to the need for emergency surgery. This emergency procedure carries a higher risk of complications compared to routine surgery.

Cataract surgery questions and procedures

Frequently asked questions of users, procedures before and after cataract surgery

  • It is advised to take a bath the night before the procedure.
  • Please avoid using any perfumes and makeup around the eyes.
  • Please refrain using soft contact lenses for a minimum 3 days, and hard lenses for 3 weeks, leading up to the operation.
  • Please inform your doctor of any drug known sensitivities to medications.

It is important to note that these actions are not painful, and your cooperation greatly influences achieving the desired outcome. Therefore, maintain composure, keep calm and pay attention the surgeon’s instructions throughout the procedure.

  • Fixate on the blinking green light and avoid moving your eyes or head during the operation.
  • The laser exposure lasts less than 20 seconds, depending on the specific type of laser being used. Therefore, refrain from moving your eyes during the time you hear the sound of the laser.
  • Rest assured about your eyelids during the operation; because they will be gently held open, minimizing any discomfort. Avoid squeezing or frowning to prevent discomfort and pain.
  • Keep your hands clear of the surgical area to prevent any potential contamination.
  • Avoid rubbing your eyes.
  • Refrain from wearing sunglasses in direct sunlight.
  • Avoid exposure to eye-watering situations in the initial day post-surgery.
  • Abstain from swimming for at least one month.
  • In case of mild discomfort and pain, consider using pain relievers.
  • It is safe to resume driving after a few days, exercising caution.
  • Avoid applying pressure to your eyes during the initial weeks.
  • Cataract surgery should be considered when the condition reaches a point where it significantly hinders daily activities. It is advisable to consult an ophthalmologist and follow their recommendation.
  • Cataracts most commonly visible in individuals over the age of 60. However, there is no specific age as various factors such as eye trauma, corticosteroid use, and even congenital factors can contribute to their development.
  • No, the pace of cataract progression varies from person to person and can even differ between the eyes of the same patient. Regular monitoring by a doctor is essential to determine the appropriate timing for surgery.
  • A “secondary cataract” refers to the clouding that occurs after cataract surgery, resulting from the accumulation of epithelial cells between the lens and the posterior capsule. This can lead to diminished vision post-surgery, but it can be addressed by using Yag laser to clear the visual pathway.
  • No, cataract surgery in infants actually stimulates the visual system, fostering the development of the optic nerve and visual center. In fact, prompt treatment of congenital cataracts is crucial, as any delay can potentially lead to amblyopia, commonly known as “lazy eye”.
  • The ideal time for cataract surgery is when vision has declined significantly, causing limitations in daily activities.
  • Yes, neither eye drops, exercises, nor glasses can prevent the development or improve the condition of cataracts. Currently, surgery is the sole treatment option, involving the removal of the clouded lens and its replacement with an artificial lens.

Yes, eye drops, exercise or glasses do not prevent cataracts from developing or improving, and currently surgery is the only treatment, which includes removing the clouded lens and replacing it with an artificial lens.
