CATARACT SURGERY
What is Cataract Surgery?
Cataract Surgery involves removing the clouded lens (cataract) and replacing it with a clear artificial lens.
The artificial lens called an Intraocular Lens or Lens Implant, is positioned in the same place as your natural lens. It remains a permanent part of your eye.
Over 98% of Cataract surgeries are successful and is one of the most successful operations in the world.
Types Of Intraocular Lens Implants
There are many different types of lens implants available for cataract patients.
Monofocal Intraocular Lens
The traditional lens implant is a mono-focal intraocular lens, which can be used to correct a certain range of vision (usually the distance vision for driving).
Multifocal Lens
These lens implants may correct different portions of your vision, which include:
- Distance,
- Intermediate (computer) and
- Near (reading) vision.
These implants may help to reduce the need for spectacles after Cataract Surgery, however, they are not suitable for all individuals.
Toric Lens
Toric lens implants can be used to correct Astigmatism and decrease the dependence on spectacles.
Your ophthalmologist will help you to choose the most suitable lens implant based on your needs and lifestyle. It is essential to appreciate that spectacles may still be required to provide the sharpest focus in certain conditions despite the most suitable implants chosen.
Preparing For Cataract Surgery
Before Cataract Surgery is performed, you may be required to,
- Have an Ocular Ultrasound test of the eye,
- Stop taking certain medications,
- Fast 8 hours before the procedure.
Procedure for Cataract Surgery
The procedure is quick, pain-free, and performed in a day surgery on an outpatient basis. Patients will spend approximately three hours at a day surgery.
The latest Cataract Surgery comprises of advanced phacoemulsification (ie ultrasound). This involves the eye's internal lens being emulsified with an ultrasonic handpiece and removed from the eye.
This process can be combined with micro-incision called Femtosecond Laser-assisted Cataract Surgery.
Five Stage Cataract Surgery
Cataract Surgery is performed in five stages, these are:
- The operated eye will be completely anaesthetised by an anaesthetic specialist,
- A small incision on the cornea is made to allow access and removal of the opaque lens,
- The cataract will be broken into small pieces with an ultrasound probe (phacoemulsification) and removed,
- After the cataract is removed, a foldable intraocular lens is then implanted into the eye for focusing light,
- Finally, the eye will be patched and the incision is then allowed to seal with the eye's natural mechanisms and you may return home. There are usually no stitches involved.
Post Cataract Procedure
Recovery is rapid and patients usually do not report any discomfort during or after surgery.
You will not be able to drive after the procedure, so you should have someone ready to take you home. You may also have to arrange for temporary home assistance.
Cataract Surgery Recovery
Post-operative eye care and wound-healing are important factors in your Cataract Surgery’s success.
Your ophthalmologist will check your eye on the following day after surgery.
- You will be instructed to use eye drops for one month.
- Depending on the severity of your cataract, your vision will clear in a couple of days or may take a few weeks.
- It is essential to understand that even if visual recovery is slower, the final visual outcome will still be the same.
Risks With Cataract Surgery
Some complications can include
- Persistent Ocular Inflammation,
- Glaucoma
- changes in eye pressure,
- Macular Oedema
- infection, or swelling of the retina at the back of the eye (cystoid macular oedema), and
- Retinal Detachment.
Rare complications such as infection (endophthalmitis) or bleeding Vitreous Haemorrhage
can also arise.
All of these complications are rare but, can lead to significant vision loss. Thus, close follow-up is required after surgery. These complications can all be treated.
Treatment Process
Preparation for Surgery
- Provide a complete list of your medications so you can be advises which to stopped prior to surgery,
- Treat any tooth, gum, bladder or bowel problems before surgery to reduce the risk of infection
- Stop anti-inflammatory medications (NSAIDs) at least seven days before the procedure.
- Stop or cut down smoking to reduce your surgery risks and improve your recovery
- Consider losing weight (if overweight) before surgery

- Do not eat or drink anything, including water, for 6 hours before surgery
- Avoid vigorous physical activity or exercise 24 hours prior to surgery,
During Surgery
- Administration of general anesthesia or sedation and local anesthesia
- The entire procedure can take 60 minutes to two hours.
- Procedure is performed and sent to recovery room, for observation
- Pain medications are prescribed to help with pain during the recovery phase.
After Surgery
- Do not consume large amounts of alcohol after surgery,
- Avoid vigorous physical activity or exercise until advised,
- Follow the Post Surgery Treatment Plan proscribed by the surgeon and post op care specialists.
