CATARACT

Surgery

Colby is a leading specialist in cataract surgery in Melbourne and is regularly invited to provide talks at conferences and seminars on intraocular lens selection. He is able to offer all forms of cataract surgery to his patients and has experience using the latest develops in lens design to enhance visual outcomes and patient satisfaction. The choice of intraocular lens is tailored completely to each patient based on their lifestyle goals, hobbies and activity

What Are Cataracts?

A cataract occurs when the natural lens of the eye becomes cloudy, typically as part of the aging process. Over time, the lens, which is normally clear in youth, becomes denser and less transparent. This clouding reduces the amount of light reaching the retina, leading to diminished visual clarity. Common symptoms include:

  • Blurred vision or glare
  • Ghosting or seeing multiple images
  • Difficulty reading or writing
  • Challenges with night vision and driving at night
  • Frequent changes in glasses or contact lens prescriptions

While early cataracts may not severely affect daily activities, their progression can significantly impact vision and quality of life. Cataract surgery offers a safe, effective solution to restore clear vision and can often remove the need to wear glasses.

About Cataract Surgery

Cataract surgery is one of the most common and successful procedures worldwide. During the surgery, the cloudy lens is removed and replaced with a clear, customised intraocular lens, which not only restores vision but often improves it beyond what it was before cataract development.

The procedure is typically performed as an outpatient surgery, using anaesthetic drops and sedation. Most patients experience significant vision improvement within 48 hours, though recovery can vary depending on age and the severity of the cataract.

If cataracts are present in both eyes, surgery is often done one eye at a time. In select cases without complicating factors, you may be offered cataract surgery on both eyes at the same time. A small incision is made in the cornea, and the cloudy lens is removed and replaced with an artificial lens. The choice of lens will be discussed with you prior to surgery, based on your visual needs and goals.

Recovery

Cataract surgery is minimally invasive, involving a small incision and no general anaesthesia, which allows for a relatively quick recovery. Most patients notice improved vision within 1-3 days. However, it’s important to follow post-operative guidelines to ensure proper healing: 

  • No driving for at least 24-48 hours 
  • Showering is fine, but avoid direct water contact with the eyes for 24-48 hours 
  • Avoid rubbing your eyes for 3-4 days 
  • Refrain from swimming, wearing eye makeup, or participating in contact sports for 7 days 

You’ll have a post-operative appointment the day after surgery to assess the healing process, with follow-up visits scheduled for one week and one month after surgery. 

In the early recovery stages, you may notice temporary visual effects such as: 

  • Shimmering or flickering 
  • Floating spots 
  • Fluctuating vision 
  • Occasional light flashes 
  • A gritty feeling in the eye 
  • A crescent-shaped shadow in your peripheral vision 

These symptoms typically subside within the first month. After cataract surgery, it’s recommended to have routine eye check-ups with your optometrist every 1-2 years to maintain overall eye health. 

Possible Risks and Complications

While cataract surgery is generally safe with a 98-99% success rate, all surgeries carry some risk. Potential complications include: 

  • Elevated eye pressure, possibly extending recovery time 
  • Swelling of the cornea, which could prolong recovery and may require additional surgery 
  • Side effects from medications 

 

Although rare, there is a small risk of serious complications, such as infection or hemorrhage, which could permanently affect vision. These risks occur in approximately 1 in 10,000 surgeries. Be sure to discuss any concerns with your surgeon during your pre-operative consultation. 

Costs

The cost to undergo cataract surgery depends on your unique circumstances. All of these circumstances will be considered when creating a package suited for your surgery. This includes if you have private health insurance, the level of hospital cover that you have and if you are a pensioner or experiencing financial hardship. My bookings coordinator will explain these details to you at the time of your consultation. For further information please contact me here.

Lens choices

Standard single focus lens

For patients with minimal astigmatism, a standard single focus intraocular lens (IOL) can provide clear, focused vision. These modern lenses are designed to offer excellent visual quality. However, the eye will be set to focus at either distance or near, so a decision must be made regarding the overall vision plan for both eyes. Some people opt to set one eye for distance and the other for near. This allows the majority of people to be spectacle independent after cataract surgery, however this can reduce depth perception in some cases.

Extended Depth of Focus lens

An extended depth of focus lens provides a broader range of vision. Typically, these lenses are designed to offer clear distance and intermediate vision, allowing you to drive and use a computer without glasses. However, you may still need reading glasses for extended close-up tasks. There are various models of EDOF lenses to accommodate different visual goals. They are less likely to have the side effects of halos and glare as multifocal lenses.

Multifocal lenses

A multifocal lens offers three distinct focal points, making it an ideal choice if you want clear vision at all distances. It provides good distance, intermediate, and near vision, meaning you likely won’t need glasses for tasks like reading. However, you may experience temporary glare or halos, especially at night, which usually diminish over the first month. The best results are often achieved when both eyes receive a multifocal IOL, but mixed options can be discussed during your consultation. The quality of distance vision is slightly reduced to allow for such a large range of vision.

Toric lenses

For patients with astigmatism, a toric lens is often necessary. Astigmatism occurs when the cornea has an uneven curvature in one direction compared to the other. Glasses can correct this, but a toric lens offers the same precision, providing clear, sharp vision. These lenses require specific axis alignment during the surgery to ensure the best visual outcomes. Toric lenses can be combined with single focus, extended depth of field and multifocal lenses to reduce the reliance on glasses after cataract surgery.

Combination with glaucoma procedures

For patients who have glaucoma and cataracts, combining the operation with the insertion of iStents can reduce the reliance on drops for glaucoma following the surgery. An iStent is a tiny device that is implanted during cataract surgery into the area that drains fluid from the eye. This works to lower the amount of water in the eye and reduce damage to the optic nerve from having high eye pressure. Colby will discuss whether iStent placement is appropriate for your level of glaucoma and how it can enhance the overall outcome of your cataract surgery.
