Understanding Astigmatism
What is Astigmatism?
Astigmatism treatments in Sydney is a common refractive error where the cornea or lens is shaped irregularly, causing blurred or distorted vision. Instead of being perfectly round like a basketball, an eye with astigmatism is more like a football, leading to light focusing unevenly on the retina.
Causes of Astigmatism
It can be hereditary or caused by:
- Eye injury
- Surgery
- Keratoconus (a progressive thinning of the cornea)
- Aging-related changes in the eye
Symptoms You Shouldn’t Ignore
- Blurred or distorted vision
- Headaches
- Eye strain
- Difficulty seeing at night
- Squinting
Diagnosis and Eye Exams
How Astigmatism is Diagnosed
An optometrist uses a series of tests like:
- Visual acuity test
- Keratometry
- Corneal topography
- Refraction assessment
Importance of a Comprehensive Eye Test
Early diagnosis ensures the best treatment outcome. If you’re in Sydney, getting regular checkups from accredited eye clinics can prevent long-term complications.
Conventional Astigmatism Treatments
Eyeglasses
This is the most basic and non-invasive way to correct astigmatism, using specially curved lenses.
Contact Lenses
Toric contact lenses are designed for astigmatism correction. However, not everyone finds them comfortable.
Refractive Surgery Options
- LASIK
- PRK
- SMILE
These work by reshaping the cornea, but not all patients qualify—especially those with thin corneas or high prescriptions.
Phakic Intraocular Lens (PIOL): A Game-Changer
What Is a Phakic Intraocular Lens?
PIOL is a tiny, implantable lens placed in the eye behind the cornea and in front of the natural lens. It works like contact lenses, but permanently stays inside the eye.
How Does PIOL Work for Astigmatism?
These lenses correct the irregular focus caused by astigmatism, offering clear, sharp vision—often without needing glasses or contacts afterward.
Advantages Over LASIK and PRK
- Suitable for high prescriptions
- Doesn’t alter corneal tissue
- Reversible
- Clear vision even in low light
Types of Phakic Intraocular Lenses Available
Implantable Collamer Lens (ICL)
The most popular PIOL, made from a biocompatible material. Brands like Visian ICL are widely used in Sydney.
Artisan/Verisyse Lenses
These are iris-clipped lenses used in specific cases, especially when ICL is not suitable.
Who Is a Candidate for PIOL?
Ideal Candidate Criteria
- Aged 21–45
- Stable prescription for at least one year
- Not suitable for LASIK
- Healthy eyes (no infections or glaucoma)
Contraindications and Considerations
- Thin anterior chamber
- Chronic dry eyes
- Pregnant or breastfeeding women
- Autoimmune diseases
The Procedure: What to Expect
Pre-operative Preparation
- Eye measurements and scans
- Discuss risks and benefits
- No contacts a week before
The Surgical Process
- Local anaesthesia
- Tiny incision made
- Lens implanted behind the iris
- No stitches required
- Outpatient procedure (takes 15-30 minutes)
Recovery Timeline and Aftercare
- Most people return to work in 2–3 days
- Mild discomfort or blurry vision initially
- Eye drops prescribed for healing
- Avoid swimming or heavy exercise for a few weeks

- Dislocation of the lens (very rare)
Comparing PIOL to Other Refractive Surgeries
PIOL vs LASIK
- PIOL suitable for high prescriptions
- LASIK has faster visual recovery
- PIOL doesn’t touch the cornea
PIOL vs PRK
- PIOL has quicker healing
- PRK preferred for thin corneas
- Less discomfort post-PIOL
PIOL vs SMILE
- SMILE is minimally invasive
- PIOL has clearer night vision
- Both offer excellent long-term outcomes
