It's likely you know of a parent or family member who has cataract or has undergone cataract surgery. That's not surprising, given that in Singapore, cataract affects around 80% of the population above 60 years old and 95% of the population above 70. In fact, more than 30% of people aged 45 and above have some degree of cataract.
The presence of other health issues, such as severe myopia, smoking, high blood pressure and diabetes, can also increase your risk of cataracts. Although the reasons are still not fully understood, people with diabetes mellitus statistically face a 60% higher risk of developing cataracts.
Cataracts are the clouding of the normally clear lens of the eyes. In the early stages, only a small part of the eye's lens is usually affected and therefore there may be no notable vision loss. As the cataract clouds more of the lens and distorts the light passing through the it, changes to the eyesight appear.
Most cataracts are due to ageing or injury in the tissue that makes up the eye lens.
They may also be a result of certain inherited genetic disorders, other eye conditions, past eye surgery or medical conditions such as diabetes.
Long-term use of steroid medications can also cause the development of cataracts.
Cataracts can develop at any age, even if you are not at high risk for it. Look out for these symptoms and consult an eye specialist to get a diagnosis, just to be safe:
The good news is cataract surgery is very common and is generally a safe procedure. Artificial lens implants such as multifocal and other lenses will be able to correct short-sightedness and long-sightedness, as well astigmatism and presbyopia, at the same time. If you are suitable for multifocal lens, you can possibly say goodbye to spectacles and go about your daily activities with near perfect vision.
An early diagnosis and timely treatment of cataract will be able to prevent the condition from worsening.
Delayed treatment may come at a time when the lens is more unstable, and when there are other complications such as glaucoma. Delayed surgery also comes with increased risk of complications, reduced success rate of the operation, and a longer recovery process with less favourable results, as compared to treating the condition early.
There are 2 main types of surgical procedures to treat cataracts.
The procedure starts off with you being slightly sedated: mild sedation is applied by an anaesthetist so you don't feel anything. Once this is done, the doctor proceeds to make a small incision at the edge of the cornea to enter the eye. They will break up the cataract using ultrasound and remove the cataract. An artificial lens will then be implanted to restore your sight. No stitches are required as the wound often seals on its own.
The entire process takes about 30 – 45 minutes and is treated as a day case so you need not stay overnight.
After surgery, you'll need to apply medicated eye drops to improve recovery and prevent infection. Your eye will usually heal thoroughly after a month.
Phacoemulsification is the standard cataract surgery procedure and has a 95% success rate. This is still the procedure of choice and is suitable for most patients.
This is similar to phacoemulsification surgery where ultrasound energy is used to break up the cataract. The difference is that laser is used to replace certain steps of the procedure. Laser-assisted cataract surgery uses a femtosecond laser to remove cataracts accurately and precisely, replacing the use of handmade incisions.
Cataract surgery is generally safe but as with any other surgery, it carries a risk of infection and bleeding.
There is also a risk of retinal detachment with the surgery. This happens when the retina, which sits all the way back in the eye pulls away from its position. Signs of retinal detachment include:
See your doctor immediately if you notice any of these signs.
Recovery from a cataract surgery is usually short and uneventful. You may find yourself easily resuming your usual activities within a day after the surgery. However, you should take extra care especially during the first week of surgery. Here are some tips you can observe to get the best recovery and prevent future complications:
There is currently not enough evidence to determine if laser-assisted cataract surgery or standard cataract surgery will result in better outcome, as it will depend on your eye condition. You should discuss with your eye specialist to decide which surgery method is more suitable for your eyes.
