Question 1

What is the downside of monovision?

Accepted Answer

Monovision, a common approach to correcting presbyopia, has notable downsides. The primary issue is the potential loss of stereopsis, or depth perception, as the brain receives a clear image from only one eye at a given distance. This can make tasks like threading a needle, pouring liquids, or judging stairs more challenging and may be particularly problematic for night driving. Some individuals also experience persistent ghosting, glare, or a sense of visual imbalance that the brain cannot fully adapt to. Furthermore, it can complicate the fitting of future premium intraocular lenses (IOLs) or laser vision correction, as the visual system has been trained to suppress one eye. A thorough consultation with an eye care professional is essential to determine if one's lifestyle and visual demands are compatible with this correction method.

Question 2

What is blended vision LASIK?

Accepted Answer

Blended vision LASIK, often referred to as presbyopia-correcting LASIK or monovision LASIK, is a specialized laser vision correction technique designed to reduce dependence on reading glasses. Instead of correcting both eyes for perfect distance vision, the procedure intentionally sets one eye (typically the dominant one) for optimal distance vision and the other eye for optimized near vision. The brain learns to blend the two images, providing a functional range of clear vision for both far-away objects and close-up tasks like reading. This approach is a popular solution for individuals over 40 experiencing presbyopia.

Question 3

Is cross linking cornea better than LASIK?

Accepted Answer

Cross-linking and LASIK are fundamentally different procedures designed for distinct purposes, making a direct comparison of "better" inaccurate. LASIK is a refractive surgery primarily used to correct common vision errors like nearsightedness, farsightedness, and astigmatism by reshaping the cornea. Corneal cross-linking (CXL) is a therapeutic treatment, not a vision-correcting procedure. Its primary purpose is to halt the progression of keratoconus or other corneal ectatic diseases by strengthening the corneal collagen fibers. For a patient with a stable, healthy cornea seeking vision correction, LASIK is the standard. For a patient with a progressive thinning disorder like keratoconus, CXL is the essential first step to stabilize the cornea; vision correction may be considered later. For individuals concerned about corneal thickness, our internal article, Thin Corneas? Alternative Vision Correction Options, explores important considerations.

Question 4

Can you get LASIK after cross linking

Accepted Answer

Yes, it is generally possible to get LASIK after undergoing corneal cross-linking (CXL), but it is a carefully managed two-stage process. Cross-linking is a procedure that strengthens the cornea, typically to treat keratoconus or corneal ectasia. It is crucial that the cornea is stable for a significant period—usually at least one to two years—after CXL before considering LASIK. The eye surgeon must conduct thorough pre-operative testing to ensure the cornea has stopped thinning and changing shape, has adequate thickness, and that the patient's prescription has remained stable. This sequential approach allows for the safe correction of refractive errors like nearsightedness or astigmatism after the underlying structural instability has been addressed. Not all patients who have had CXL will be suitable candidates for LASIK, and alternative vision correction options may be discussed.

Question 5

LASIK Xtra

Accepted Answer

LASIK Xtra is a combined procedure that integrates traditional LASIK surgery with a corneal cross-linking (CXL) treatment. This approach is designed to enhance the structural integrity of the cornea by creating additional bonds between collagen fibers. It is often recommended for patients with thinner corneas or those at a higher risk for post-LASIK ectasia, a condition where the cornea bulges and distorts vision. The cross-linking component acts as a preventive reinforcement. For a detailed discussion on when this combined approach is medically indicated, please refer to our internal resource, Corneal Cross-Linking With LASIK: When It&#8217;s Needed. The decision to proceed with LASIK Xtra requires a thorough preoperative evaluation by a qualified ophthalmologist to assess corneal topography, thickness, and overall eye health.

Question 6

I had LASIK 20 years ago can I have it again

Accepted Answer

Yes, it is often possible to have a LASIK enhancement procedure, even 20 years after your initial surgery. This is commonly referred to as a "touch-up" or "revision." The primary determining factors are the current thickness and health of your corneal tissue, as sufficient corneal thickness must remain to safely perform the laser ablation. Your overall eye health, the stability of your current prescription, and the specific reason for vision changes (like presbyopia or a slight regression) will be thoroughly evaluated. A comprehensive consultation with an ophthalmologist is essential. They will perform advanced diagnostic tests to map your cornea and determine if you are a suitable candidate for a repeat procedure or if an alternative vision correction option would be more appropriate.

Question 7

LASIK eye surgery cost

Accepted Answer

The cost of LASIK eye surgery varies significantly based on technology, surgeon experience, and geographic location. On average, the price per eye in the United States ranges from $1,500 to $3,000, making the total procedure cost typically between $3,000 and $6,000. This fee generally includes pre-operative consultations, the surgery itself, and post-operative care. It is crucial to understand that this is an elective procedure often not covered by standard health insurance, though many providers offer financing plans. When evaluating cost, prioritize the surgeon's qualifications and the technology used over price alone.
