Unveiling the Risks of Cataract Surgery

written by

How serious is cataract surgery? Cataract surgery is a transformative medical procedure that has provided countless individuals with renewed clarity and improved vision. As one of the most commonly performed surgeries worldwide, it has proven to be a reliable solution for those grappling with the visual impairment caused by cloudy lenses. However, like any medical intervention, cataract surgery is not without its inherent risks and considerations. In this article, we delve into the multifaceted landscape of cataract surgery, shedding light on the potential dangers of cataract surgery that individuals should be aware of before embarking on this journey towards clearer vision. As we unravel the complexities surrounding the procedure, our aim is to empower readers with the knowledge needed to make informed decisions about their eye health.

What is a cataract?

What is a cataract?

How dangerous is cataract surgery? Before learning the answer, let’s talk about the cataract itself. A cataract is a clouding of the natural lens in the eye that affects vision. The lens, which is typically clear, becomes cloudy over time, causing blurred or hazy vision. Cataracts commonly develop with age, but they can also result from injury, certain medications, or medical conditions. Symptoms may include difficulty seeing in low light, increased sensitivity to glare, and a gradual decrease in vision. Cataract surgery is a common and highly effective procedure to remove the cloudy lens and replace it with an artificial lens, restoring clear vision.

Is surgery necessary?

If you are dealing with cataracts, the choice to undergo cataract surgery ultimately rests with you.

Cataracts typically progress gradually over time, and surgery to replace the clouded lens is the sole method to enhance your vision.

On the NHS, surgery is generally offered if your cataracts are impacting your eyesight and overall quality of life.

It’s essential not to base the decision solely on your eye test (visual acuity) results. Personal factors, such as your daily activities, hobbies, and interests, may also play a role in your decision to opt for surgery.

If you prefer, you can postpone surgery and opt for regular check-ups to monitor the situation. No medications or eye drops have been scientifically proven to improve or halt the progression of cataracts.

How is the surgery done?

Is cataract surgery dangerous? No, as long as the procedure is conducted by a skilled professional, and you adhere to all of their recommendations.

Prior to the surgical procedure, your surgeon will assess your eye to calculate the appropriate focusing power for your intraocular lens (IOL). Additionally, you will be inquired about any medications you are currently taking, and you may be advised to refrain from certain medications leading up to the surgery.

Furthermore, your surgeon may prescribe pre-surgery eye drop medications. These medications serve the purpose of preventing infection and minimizing swelling both during and after the surgery.

Cataract surgery, typically conducted on an outpatient basis, is a procedure that usually lasts an hour or less. The initial steps involve administering eye drops to dilate the pupil and providing medications to numb the area, potentially accompanied by a relaxing sedative. During the surgery, the clouded lens is removed, and a clear artificial lens is typically implanted. However, in some cases, a cataract may be removed without the insertion of an artificial lens.

Two surgical methods are commonly used for cataract removal:

  1. Phacoemulsification (Ultrasound Method): This technique involves making a tiny incision in the front of the eye (cornea). A needle-thin probe is inserted into the lens where the cataract has formed. The surgeon utilizes the probe, which transmits ultrasound waves, to break up the cataract and suction out the fragments. The lens capsule at the back of the eye is preserved for the artificial lens placement. Stitches may be employed to close the small corneal incision after completing the procedure.
  2. Extracapsular Cataract Extraction: This less common method necessitates a larger incision compared to phacoemulsification. Through this incision, tools are used to remove the front capsule of the lens and the cloudy lens in one piece. The back capsule of the lens remains in place to serve as a platform for the artificial lens. This approach may be chosen in cases of specific eye complications, and stitches are required due to the larger incision.

Following the removal of the cataract through either phacoemulsification or extracapsular extraction, the artificial lens is implanted into the now-empty lens capsule.

After cataract surgery, vision improves within days, though initial blurriness is normal during the healing process. Cataracts, usually yellow or brown-tinted before surgery, dull color perception. Post-surgery, colors appear brighter through the new, clear lens. Follow-up visits with the eye doctor occur a day or two, a week, and around a month after surgery to monitor healing. Expect mild discomfort and itching for a few days—avoid eye rubbing. An eye patch or shield may be recommended, especially during sleep. Prescribed eye drops or injections prevent infection, reduce swelling, and control eye pressure. Discomfort typically diminishes within days, with complete healing often achieved in eight weeks.

Is cataract surgery dangerous? As with any surgical procedure, cataract surgery comes with inherent risks and potential complications. Here are some cataract surgery risks:

  1. Eye infection.
  2. Bleeding in the eye.
  3. Persistent swelling of the front or inside of the eye.
  4. Retinal swelling (in the nerve layer at the back of the eye).
  5. Detached retina (lifting of the retina from the back of the eye).
  6. Damage to other eye structures.
  7. Intractable pain unresponsive to over-the-counter medication.
  8. Blurred vision.
  9. Perception of halos, glare, and dark shadows.
  10. Vision loss.
  11. Dislocation of the intraocular lens (IOL), shifting out of position.

It is important to note that while cataract surgery can address cataract-related vision issues, it cannot restore vision lost due to other eye conditions such as macular degeneration, glaucoma, or diabetic retinopathy.

In conclusion, while cataract surgery is a common and generally safe procedure, it is crucial for individuals to be aware of the potential risks and complications associated with it. Like any surgical intervention, there is a range of possible issues, from infections and bleeding to changes in vision and discomfort. However, these risks must be weighed against the potential benefits of improved eyesight and enhanced quality of life. It is essential for patients to engage in open communication with their healthcare providers, discuss any concerns, and carefully follow post-operative instructions to minimize the likelihood of complications. As with any medical decision, an informed and collaborative approach between patients and their medical teams is key to ensuring the best possible outcomes. We hope we helped you to find the answer to the question “How safe is cataract surgery?”

Is cataract surgery considered a high-risk procedure? 

Cataract surgery is conducted by an eye doctor, known as an ophthalmologist, and is typically performed on an outpatient basis, eliminating the need for a hospital stay post-surgery. This procedure is widespread and is generally deemed safe.

Who should refrain from undergoing cataract surgery?

Cataract surgery may not be suitable for individuals who:
Are in poor health or dealing with a serious medical condition.
Have advanced macular degeneration.
Experience a detached retina.
Have eye-related medical conditions, such as an infection.
Suffer from advanced diabetes affecting the retina.
Have corneal diseases like glaucoma.

What other options are available instead of cataract surgery? 

Symptoms of cataracts can potentially be alleviated through the use of new eyeglasses, anti-glare sunglasses, or magnifying lenses. Additionally, specific tints and coatings can be applied to lenses to minimize symptoms. Improving the positioning of lamps or reading lights may also provide some relief.
