Intraocular Lens (IOL) implantation is an option for individuals looking to correct vision problems associated with cataracts. There are different types of IOLs for varying vision problems. With over 35% of the population in Sydney using vision impairment solutions, such surgeries provide the perfect permanent fix. However, many remain apprehensive about opting for an intraocular lens implant in Sydney. Worry not because this guide details everything you need to know about the procedure.
What Is the IOL Procedure?
An intraocular lens (IOL) is the implantation of a small plastic lens in the eye. It replaces your natural lens when it has become cloudy or opaque due to cataracts. It offers several advantages over other types of treatment for cataracts, such as surgery and laser therapy:
- There are no cuts or incisions during this procedure; therefore, there is less risk of infection and pain associated with the surgical procedure. Less invasive procedures have always been a popular choice in Sydney!
- The IOL is permanent—it does not need removal at any time in the future.
Types of IOL
- Monofocal IOLs: They are ideal for patients who need a single focus, such as reading or distance vision. Doctors use them to correct nearsightedness, farsightedness and astigmatism.
- Bifocal IOLs: These lenses provide two different focal points in one lens, allowing patients to see far-away objects and close-up details without glasses or contacts. Patients with presbyopia (the loss of accommodation due to ageing) may also find bifocal contacts useful; however, they will still require reading glasses in addition to their contact lens correction.
- Multifocal Intraocular Lenses (IOL): These lenses allow you to see your surroundings clearly while simultaneously providing an extra focus on things that would normally require reading glasses—making them an excellent choice for people with presbyopia who do not wish to rely on reading glasses or bifocals. MIOLs are also marketed under the brand names Accommodating IOLs, Accommodation Enhancing Intraocular Lens’or Accommodating RGPs (Rigid Gas Permeable).
Tips Before Opting for Intraocular Lens Implant
As a patient, you must get a thorough eye exam before opting for an Intraocular Lens (IOL) implant. Any qualified doctor in Sydney will assess your eyes and determine whether you are eligible for the procedure. During this screening, your doctor will also discuss risks associated with the procedure as well as any side effects that may occur after surgery.
One major risk associated with IOL implants is cataract development which can happen if your intraocular lens does not fit properly within your eye or if it migrates away from its proper position in your eye after placement. This can cause inflammation around the cornea and lead to ulceration of this sensitive part of our body, resulting in blurry vision and discomfort while blinking. Consider all risks and rewards before signing up for an intraocular lens implant in Sydney.
Refractive Lens Exchange
A cataract is a clouding of the eye’s lens, which causes a loss of vision. The lens usually begins to lose its clarity as you age and may develop a cataract at any age. In Sydney, over 27% of the population over 65 years faces some cataract deterioration.
When you are younger, your eyes can focus on objects close up or far away without needing glasses or contact lenses. But if you have an eye disease called presbyopia, it becomes harder for you to focus on near objects as you get older (usually around 40 years old). This makes it difficult to read small print or thread a needle without glasses or contacts.
Refractive Lens Exchange (RLE) is one option for treating cataracts because the cornea may no longer be clear after the patient has had many years of uncorrected vision through the natural lens causing refractive problems such as astigmatism, myopia and hyperopia (long-sightedness).
