If you have glaucoma and are considering vision correction, you’re probably wondering how this condition affects your options. Understanding the relationship between glaucoma and LASIK helps you have clearer conversations with your eye care team and make decisions that protect your long-term vision health.
Can a Person with Glaucoma Have LASIK Surgery?
LASIK may be possible if your glaucoma is well-controlled, but the decision depends on whether your doctor can still monitor the disease accurately afterward. People with advanced or unstable glaucoma are usually not candidates.
Because LASIK changes corneal thickness and curvature, it can make intraocular pressure (the fluid pressure inside your eye) read lower than it actually is. Since pressure tracking is essential for preventing optic nerve damage, this issue must be reviewed carefully.
If your glaucoma doctor confirms that monitoring will remain reliable, LASIK can correct your refractive error, but it does not treat or reverse glaucoma. You would continue your glaucoma care exactly as before, with long-term follow-up built into your plan.
Considerations for Patients with Glaucoma
Several important factors determine whether LASIK might be an option for someone with glaucoma. Your eye surgeon will carefully evaluate these elements before making any recommendations.
Current Glaucoma Control Status
How well your glaucoma is currently managed matters significantly. If your eye pressure is stable, your optic nerve shows no recent damage, and your visual field tests remain consistent, you’re in a better position to consider vision correction procedures. Uncontrolled glaucoma with fluctuating pressures or progressive vision loss makes LASIK inadvisable since the procedure could interfere with accurate monitoring.
Type and Severity of Glaucoma
Primary open-angle glaucoma that’s caught early and well-controlled presents different considerations than advanced glaucoma or angle-closure forms. The type of glaucoma you have affects both your candidacy and which alternative procedures might work better. Advanced glaucoma with significant optic nerve damage typically rules out LASIK entirely.
Corneal Thickness and Health
LASIK requires sufficient corneal thickness since the procedure removes tissue to reshape your cornea. Patients with glaucoma often have thinner corneas or have undergone previous glaucoma surgeries that affect corneal structure. Your surgeon needs adequate tissue to work with while leaving enough cornea to maintain structural integrity and allow for accurate pressure measurements.
Medication Requirements
The glaucoma medications you currently use can influence surgical decisions. Some medications affect healing or increase surgical risks. Your ophthalmologist needs to understand your complete medication regimen to assess how it might interact with LASIK and recovery.
Long-Term Monitoring Needs
Glaucoma requires lifelong monitoring of eye pressure and optic nerve health. Because LASIK changes corneal thickness, it can make traditional pressure measurements less accurate. Your doctor needs to ensure they can still reliably monitor your glaucoma after any refractive surgery, which may require different measurement techniques or equipment.

How to Prepare for Glaucoma Laser Surgery
If you and your ophthalmology team decide that LASIK is appropriate despite your glaucoma diagnosis, thorough preparation is essential to minimize risks and optimize outcomes.
Step 1: Comprehensive Pre-Operative Evaluation
Schedule appointments with both your glaucoma specialist and refractive surgeon to ensure complete coordination of care. These evaluations will include detailed corneal measurements, current IOP readings using multiple techniques, optic nerve imaging, visual field testing, and a review of your complete glaucoma treatment history.
Step 2: Optimize Glaucoma Control
Work with your glaucoma doctor to ensure your intraocular pressure is at its most stable point before surgery. This may involve adjusting medications or timing the procedure strategically. Document baseline IOP measurements using various techniques to establish reference points for post-operative monitoring.
Step 3: Discontinue Contact Lenses
If you wear contact lenses, you’ll need to stop wearing them for a period before your pre-operative measurements and surgery. Soft lenses typically require removal for at least two weeks, while rigid gas permeable lenses may need to be discontinued for three to four weeks to allow your cornea to return to its natural shape.
Step 4: Arrange Post-Operative Support
Plan for someone to drive you home after surgery and assist you during the first 24 hours of recovery. Stock up on prescribed eye drops and any glaucoma medications you’ll need to continue after LASIK.
Step 5: Establish Long-Term Monitoring Plan
Before proceeding with surgery, confirm that you have a clear plan for ongoing glaucoma monitoring after LASIK. This should include scheduled follow-up appointments with both your refractive surgeon and glaucoma specialist, understanding which IOP measurement techniques will be used, and knowing what correction factors may need to be applied to your readings.
What to Expect After LASIK for Glaucoma
Recovery from LASIK when you have glaucoma requires more careful attention than standard LASIK recovery, with special focus on both healing and ongoing disease management.
Immediate Post-Operative Period (First 24-48 Hours)
Your vision will likely be blurry immediately after surgery, with gradual improvement over the first day. You’ll experience some discomfort, light sensitivity, and watering, which are normal healing responses.
Continue all prescribed glaucoma medications unless specifically instructed otherwise by your doctor. Your surgeon will provide antibiotic and anti-inflammatory drops in addition to your glaucoma medications, so following the correct schedule for multiple medications is crucial.
First Week of Recovery
Most patients notice significant vision improvement within the first few days, though fluctuations are normal. Avoid rubbing your eyes, which is especially important when you have glaucoma, because any trauma could affect your optic nerve or IOP.
Attend all scheduled follow-up appointments with your refractive surgeon to monitor healing and check for complications. Your glaucoma specialist should also evaluate you during this period to assess any changes in intraocular pressure related to the surgery.
First Month After Surgery
Your vision will continue stabilizing, and you’ll gradually reduce the post-operative anti-inflammatory drops as directed. However, you’ll continue your regular glaucoma medications throughout this period.
Your care team will begin establishing new baseline IOP measurements using techniques appropriate for post-LASIK corneas. This is when your doctors will determine what correction factors need to be applied to your pressure readings going forward.
Long-Term Follow-Up and Monitoring
Expect more frequent follow-up appointments than standard LASIK patients require, particularly with your glaucoma specialist. Your monitoring schedule will likely include visual field tests every six to twelve months, optic nerve imaging to detect any structural changes, and IOP checks using multiple measurement techniques.
You may need to see your glaucoma doctor every three to four months initially, then adjust based on your stability. Understanding that LASIK changes how your glaucoma is monitored for the rest of your life is essential for maintaining your eye health.
What Are The Best Vision Correction Alternatives for Glaucoma Patients?
If LASIK isn’t the best match for your glaucoma situation, you have other effective vision correction options to explore. Several procedures offer different approaches that may work better with your glaucoma management while still helping you see more clearly. Each option has unique benefits worth considering as you and your doctor determine the right path forward.
PRK (Photorefractive Keratectomy)
This procedure corrects vision by gently reshaping the corneal surface without creating a flap. PRK can be a good option for patients with thinner corneas or those who need to preserve deeper corneal structure.
Recovery takes a bit longer than LASIK, but many patients achieve excellent results. For those managing glaucoma, PRK offers the benefit of maintaining more natural corneal integrity, which can help keep pressure measurements reliable over time.
SMILE (Small Incision Lenticule Extraction)
SMILE is a laser procedure type offered at some centers. Like LASIK and PRK, it removes corneal tissue, so it shares the same considerations for patients managing glaucoma. Feinerman Vision does not perform SMILE. For patients with glaucoma considerations who are not LASIK candidates, Dr. Feinerman typically discusses PRK or the EVO ICL™, which removes no corneal tissue.
ICL (Implantable Collamer® Lens)
This option places a corrective lens inside your eye rather than altering your cornea. ICL works well for patients with higher prescriptions or those whose corneas aren’t suited for laser procedures.
Because your cornea remains unchanged, your eye pressure measurements stay consistent, and your glaucoma care continues without added complexity. The lens can also be removed if your needs change, giving you flexibility as your eye health evolves.
