LASIK for Surgeons: Tackling Fogged Glasses in the Operating Theatre

Surgical vision needs to be reliable.

Whether you are performing microsurgery, operating under magnification, or working in a high-pressure environment, even a brief loss of clarity can affect performance. For many surgeons, this becomes most apparent when dealing with fogged glasses in theatre.

At Eye & Laser Surgeons in Sydney, we commonly see surgeons experiencing this issue in theatre.

The Problem: Fogged Glasses During Surgery

Fogging is not just inconvenient.

It introduces:

• interruptions in visual continuity
• risk of infection – your hands are sterile
• reduced contrast
• small but meaningful delays in response

In surgery, where precision is critical, these factors matter.

Why Do Glasses Fog in Theatre?

Fogging occurs when warm air from your mask rises and condenses on cooler lenses.

Although strategies such as:

• tightening mask fit
• using anti-fog coatings
• adjusting eyewear

can help, they rarely eliminate the problem entirely. These are workarounds, not solutions.

LASIK: Removing the Variable

For many surgeons, LASIK (laser vision correction) offers a more definitive solution.

By correcting vision at the level of the cornea, LASIK removes the need for glasses during surgery.

No lenses
No condensation surface
No fogging

This is the key advantage.

Why LASIK Matters for Surgeons

The benefit is not cosmetic—it is functional.

1. Continuous Visual Clarity

No interruption from fogging during critical surgical steps.

2. Consistent Optical Performance

Vision remains stable across:

• long procedures
• warm theatre environments
• high-stress situations

3. Reduced Cognitive Load

No need to adjust glasses or manage fogging.

Assessment and Surgical Demands: Getting the Right Outcome

Choosing the right approach to laser vision correction is not just about prescription.

For surgeons, assessment must consider:

• time spent in theatre
• duration of procedures
• reliance on magnification
• need for consistent, uninterrupted vision

A detailed evaluation includes:

• corneal thickness and shape
• tear film and ocular surface
• visual requirements specific to surgical practice

The goal is not just good vision, but reliable vision under surgical conditions

This approach is informed not only by clinical assessment, but also by experience in high-performance visual environments.

Dr Daya Sharma regularly works with individuals whose visual demands extend beyond everyday vision. This includes athletes who rely on precise, consistent visual performance under pressure—similar in many ways to the demands placed on surgeons in theatre. Through his work screening vision for Cricket Australia and Cricket NSW, the focus has been on optimising visual clarity, stability and reaction time in high-performance environments. These same principles apply to surgeons, where even small variations in vision can affect performance.

What About Other Laser Vision Correction Options?

While LASIK is the most commonly searched and performed procedure, it is not the only option.

SMILE (Small Incision Lenticule Extraction)

• Minimally invasive approach
• May be suitable in certain ocular surface conditions

PRK (Photorefractive Keratectomy)

• No corneal flap
• Useful in selected corneal profiles

Laser Vision Correction (General Term)

LASIK, SMILE and PRK are all forms of laser vision correction.

The most appropriate procedure depends on:

• corneal anatomy
• lifestyle
• visual requirements

Refractive Lens Exchange (RLE)

For some surgeons—particularly over 45 years of age —refractive lens exchange may be considered.

This can provide:

• stable distance vision
• reduced reliance on glasses
• long-term visual consistency

Workarounds vs Long-Term Solutions

Most surgeons:

• tolerate fogging
• adapt their workflow
• rely on temporary fixes

However, these approaches introduce variability.

LASIK and other forms of laser vision correction remove that variable entirely.

Optimising the Eye Before Laser Vision Correction

Laser vision correction isn’t just about fixing the prescription — the tear film and ocular surface need to be optimised first.

Dry eye is common in surgeons and can lead to:

• Fluctuating vision
• Reduced clarity under the microscope
• Less predictable outcomes after surgery

Where IPL Fits In

For some patients, Intense Pulsed Light (IPL) therapy is used before laser vision correction to improve the tear film.

It works by:

• Reducing inflammation
• Improving meibomian gland function
• Stabilising vision

Why It Matters

In surgery, even small visual fluctuations matter.

If your glasses fog up and your hands are sterile, you can’t even adjust or clean them yourself — you have to rely on a scrub nurse to step in. It’s a small interruption, but in a high-precision environment, it breaks flow and focus.

Optimising the eye first helps ensure clear, stable, reliable vision — exactly what you need in theatre.

Is LASIK Necessary for Surgeons?

No.

Many surgeons perform at a high level with glasses.

However, the question is:

Is it optimal?

Conclusion

Fogged glasses represent a small but real limitation in surgical performance.

While workarounds exist, LASIK—and other forms of laser vision correction such as SMILE and PRK—offer a more consistent solution:

• stable
• predictable
• independent of environment

For surgeons, that can make a difference.

Frequently Asked Questions

What does “LASIK” mean in this context?

In general use, “LASIK” is often used as a broad term for laser vision correction. However, there are several different procedures, including LASIK, SMILE, PRK and refractive lens exchange. The most appropriate option is determined during consultation based on your eye anatomy, prescription and visual requirements.

How long will I need off work after laser vision correction?

This depends on the procedure performed. Many patients return to normal daily activities within a few days after LASIK or SMILE, while PRK may involve a longer recovery period. The exact timing depends on your healing and the visual demands of your work.

How soon can I return to operating after LASIK or laser vision correction?

This varies depending on the individual and the type of procedure. Some surgeons return to non-surgical duties within a few days, but returning to operating typically requires stable, reliable vision. This is assessed on a case-by-case basis during follow-up.

What are the different options for vision correction?

Options include LASIK, SMILE, PRK and, in some cases, refractive lens exchange. All aim to reduce dependence on glasses or contact lenses, but they differ in technique, recovery and suitability.

Is LASIK the best option for surgeons?

Not necessarily. While LASIK is the most commonly performed and well-known procedure, SMILE or PRK may be more appropriate in certain situations. The choice depends on factors such as corneal thickness, ocular surface health and lifestyle.

Will laser vision correction eliminate fogging completely?

By removing the need for glasses, laser vision correction removes the surface on which condensation forms. However, overall visual quality and comfort still depend on factors such as tear film stability and ocular surface health.

Is laser vision correction suitable for everyone?

Not all patients are suitable candidates. A detailed assessment is required to evaluate corneal shape, prescription, ocular surface and overall eye health before determining suitability.

What is refractive lens exchange and when is it considered?

Refractive lens exchange is a lens-based procedure that may be considered in certain patients, particularly those over 45 or with early lens changes. It is one of several options discussed during consultation.
