Understanding Astigmatism and How It Affects Your Vision
What is astigmatism?
Your cornea should be shaped like a football, but with astigmatism, it resembles a rugby ball instead. This irregular curvature changes how light enters your eye and prevents it from focusing sharply on the retina at the back of your eye. You get multiple focal points instead of one clear focal point, which creates blurred or distorted images. Astigmatism develops in early childhood or during your teens. The exact causes remain unknown, although genetics can play a part. Eye injuries, surgery, or eye disease can also trigger astigmatism. Popular belief suggests that watching television, using screens, or reading in poor light causes or worsens the condition, but this is false.
Types of astigmatism
Astigmatism falls into two categories: regular and irregular. Regular astigmatism occurs when your cornea curves more in one direction than the other, with the principal meridians perpendicular to each other. Glasses, contact lenses, or refractive surgery can correct this type. Irregular astigmatism happens when the principal meridians aren’t perpendicular. This causes the cornea to curve in multiple directions. Eye injuries and conditions such as keratoconus can cause this type.
You can also have corneal astigmatism (irregularly shaped cornea) or lenticular astigmatism (irregularly shaped lens inside your eye). Astigmatism often appears with other vision conditions. Myopic astigmatism means one or both meridians are nearsighted, whilst hyperopic astigmatism indicates farsightedness in one or both meridians. Mixed astigmatism occurs when one meridian is nearsighted, and the other is farsighted.
Common symptoms you shouldn’t ignore
Astigmatism creates distinct symptoms that affect your daily life:
- Blurred or distorted vision at all distances
- Headaches when trying to focus
- Eye strain or discomfort, especially after screen use
- Difficulty with night vision
- Squinting
High astigmatism that develops in early childhood can cause lazy eye. Astigmatism may affect reading or concentration in children.
How astigmatism is diagnosed
Astigmatism is diagnosed through a complete eye exam. Your eye doctor will perform several tests that include a refraction test to determine how your eyes bend light. Keratometry measures the curvature of your cornea, whilst visual acuity tests assess your vision at different distances using an eye chart. Corneal topography generates a complete map of your cornea’s shape and provides a detailed analysis.
Can Laser Eye Surgery Correct Astigmatism?
How laser eye surgery works for astigmatism
Astigmatism laser eye surgery corrects your vision by reshaping the cornea. The procedure uses precision lasers to remove microscopic amounts of corneal tissue and smooths the irregular curvature into a more symmetrical surface. Light can then focus properly on the retina rather than splitting into multiple focal points. Detailed scans map your cornea to determine the degree and axis of your astigmatism before treatment. Advanced wavefront-guided technology tailors the correction to your unique eye profile and maximises clarity. The cornea then heals and stabilises naturally. Most patients notice improvement within days.
Success rates and what to expect
Can laser eye surgery fix astigmatism? The results speak for themselves. Studies show that more than 90% of patients achieve 20/20 vision or better, whilst 99% reach 20/40 vision or better. Satisfaction rates exceed 95%. Most FDA-approved laser platforms can treat up to 5 to 6 diopters of astigmatism. Astigmatism of 1.00 diopter or less is mild. Moderate astigmatism ranges from 1.00 to 2.00 diopters, and anything above 2.00 diopters is considered severe.
LASIK vs LASEK vs SMILE for astigmatism
LASIK treats myopia, hyperopia and astigmatism. Most patients achieve functional vision within 24 hours, which makes recovery fast. LASEK preserves the epithelial layer and suits those with thinner corneas or higher prescriptions. Recovery takes longer as the surface layer regrows over a week or so. SMILE treats myopia and astigmatism but cannot correct long-sightedness. The procedure involves a tiny incision of around 2 to 4 millimetres and is the least invasive option.
Does astigmatism come back after surgery?
Most cases show it doesn’t. Laser surgery reshapes the cornea permanently. But your eyes can still change over time due to age-related factors. The original correction remains stable, but conditions like presbyopia or cataracts may affect your vision eventually. Enhancement procedures can restore clarity if minor regression occurs.
Am I Suitable for Laser Eye Surgery with Astigmatism?
Age and prescription requirements
You must be at least 18 to qualify for laser eye surgery with astigmatism. But your prescription needs to remain stable for 12 to 24 months beforehand. Eyes often continue changing through your early twenties. Many surgeons prefer patients aged 21 or older for this reason. Astigmatism laser eye surgery treats up to 6.0 dioptres. The safe limit for myopia sits around -8 to -10 dioptres. Hyperopia correction reaches about +4 to +6 dioptres. Your corneal thickness determines these thresholds, and it varies between people.
Health conditions that may affect suitability
Certain conditions exclude you from treatment. Autoimmune diseases such as lupus and rheumatoid arthritis impair wound healing. Uncontrolled diabetes affects healing capacity. Keratoconus and corneal ectasia create structural weakness. Moderate to severe dry eye worsens post-surgery. Pregnancy and hormone-fluctuating conditions cause refractive instability.
Severe astigmatism: what are your options?
Implantable contact lenses suit prescriptions from -10.00 to -20.00 dioptres if your prescription exceeds laser limits. Refractive lens exchange benefits those aged 40+ with early cataracts.
The importance of a complete eye assessment
Pre-surgery testing determines your suitability through corneal topography, tomography, pachymetry, tear film assessment and medical history review[162]. These evaluations ensure both safety and optimal outcomes.
What You Need to Know Before Booking Your Consultation
Questions to ask your surgeon
Your original consultation determines treatment success. Ask about your surgeon’s experience performing laser eye surgery with astigmatism, their complication rates, and which technology they’ll use for your procedure. Clarify whether you’re suitable and what results you can expect. Knowing the risks specific to your case allows informed decision-making.
Understanding the procedure timeline
The surgery itself takes 20 to 30 minutes. You’ll receive local anaesthetic eye drops or, for certain procedures, general anaesthesia. Both eyes are treated on the same day, though some lens surgeries require separate appointments. You’ll go home the same day.
Cost of laser eye surgery with astigmatism
Expect to pay £1,191 to £3,970 per eye, with most spending £1,588 to £2,779. Costs vary based on technology, surgeon expertise, and location. Insurance covers elective procedures rarely, but Health Savings Accounts and Flexible Spending Accounts offer tax-free payment options.
Recovery expectations and aftercare
Vision improves within hours, though full stabilisation takes three to six months. Use prescribed antibiotic and anti-inflammatory drops for one week. Avoid rubbing your eyes and swimming initially, along with eye makeup. Attend follow-up appointments at 24 hours and one week, then throughout the first six months.
Risks and how they’re minimised
Serious complications occur in less than 1% of cases. Common temporary effects include dry eyes, affecting 60 to 70% of patients, plus glare and halos around lights. Your detailed pre-operative assessment identifies risk factors early and ensures appropriate treatment planning.
Conclusion
Laser eye surgery with astigmatism offers life-changing results for the most suitable candidates. Success depends on choosing the right procedure for your specific needs and ensuring you meet the eligibility criteria. Book a complete eye assessment to determine your suitability before you decide. Your prescription and corneal thickness will guide which treatment delivers the best outcome. With proper evaluation and experienced care, you’re one step closer to clear, spectacle-free vision.
FAQs
Q1. Can laser eye surgery correct astigmatism effectively? Yes, laser eye surgery can successfully correct astigmatism. Studies show that more than 90% of patients achieve 20/20 vision or better, with 99% reaching 20/40 vision or better. The procedure works by reshaping the irregular cornea to allow light to focus properly on the retina, creating a more symmetrical surface that corrects the blurred or distorted vision caused by astigmatism.
Q2. Is it possible to have laser surgery on both eyes during the same appointment? Yes, both eyes are typically treated on the same day during laser eye surgery. The entire procedure takes approximately 20 to 30 minutes, and you’ll be able to go home the same day. However, for certain lens surgeries, separate appointments may be required depending on your specific treatment plan.
Q3. How safe is laser eye surgery for treating astigmatism? Laser eye surgery for astigmatism is very safe, with serious complications occurring in less than 1% of cases.
