What Is Candidacy Screening?
Candidacy screening is a comprehensive preoperative evaluation that determines whether laser eye surgery may be a safe and appropriate option for your eyes. According to the American Academy of Ophthalmology's EyeWiki, this evaluation is "an extremely important and structured examination to determine if a patient is a good candidate" for procedures like LASIK, PRK, or SMILE. [S1]
The screening process goes beyond a standard eye exam. It involves detailed mapping of your cornea, measurement of thickness, assessment of pupil response in varying light conditions, and evaluation of tear film quality. These tests help identify patients who may have higher risk for complications or unsatisfactory outcomes. Understanding what screening entails—and what it costs—helps you plan your medical tourism journey more effectively.
For patients considering treatment abroad, candidacy screening serves a dual purpose: confirming surgical eligibility and establishing a baseline for informed consent. The screening results typically belong to the evaluating provider and may not transfer to another clinic, so you would need to complete screening at your intended surgical location or arrange for records review in advance.
Understanding the Screening Process
The preoperative evaluation includes several key components that together provide a complete picture of your ocular health. Visual acuity and refraction testing establishes your current prescription through both manifest and cycloplegic examinations, which temporarily relaxes the eye's focusing muscles for more accurate measurements. [S1]
Corneal topography and tomography create detailed maps of your cornea's shape and curvature, revealing any irregularities that might affect surgical outcomes. This is particularly important because LASIK involves reshaping the cornea, and the procedure requires sufficient corneal thickness to create a stable flap. Pachymetry, or corneal thickness measurement, directly informs this safety assessment.
Screening Duration
A comprehensive candidacy screening typically takes 2-3 hours and may include pupil dilation, which temporarily affects near vision.
Dry eye evaluation, including tests like Schirmer's test and tear break-up time assessment, identifies patients who may need treatment before surgery or who might experience worsened dry eye symptoms postoperatively. Wavefront analysis detects higher-order aberrations that standard prescriptions might miss, helping determine whether custom or wavefront-guided treatment could be beneficial. [S1]
Pupil measurement in various lighting conditions assesses your risk for postoperative visual disturbances like glare or halos, particularly in low-light environments. This information helps both you and your surgeon understand potential limitations and set realistic expectations.
Candidacy Screening Costs: Turkey vs. Other Markets
Understanding cost structures helps you compare options effectively and avoid unexpected expenses. In the United States, LASIK screening is often included in the surgical quote when you proceed with surgery, but standalone screening appointments may cost between $150 and $500 depending on the provider and geographic location. [S3]

$1,000-$2,500 per eye
Turkey's medical tourism model typically bundles screening within comprehensive surgery packages ranging from $1,000 to $2,500 per eye, which may include the procedure, preoperative evaluation, and postoperative care. This bundled approach differs from the US model where costs are often itemized separately. The MarketScope 2020 report cited by NVISION Eye Centers found that LASIK averages $2,632 per eye in the US market, while Turkish providers offer comparable procedures at lower price points. [S5]
When evaluating costs, consider what is included in the quoted price. Ask whether the screening fee is applied toward surgery costs if you are deemed eligible, and clarify the refund or credit policy if you are found ineligible. Some providers offer free initial consultations, while others charge separate fees for comprehensive evaluations. Understanding these distinctions prevents confusion and helps you compare offers accurately.
Who May Not Be Eligible for LASIK?
Not everyone who desires laser eye surgery meets the clinical criteria for safe treatment. Research indicates that approximately 15-20% of patients who seek LASIK consultation are ultimately deemed ineligible, according to NVISION Eye Centers clinical data. [S2]
Common Ineligibility Factors
Corneal thickness insufficient for safe flap creation
Unstable vision prescription (changes within 1-2 years)
Active ocular conditions (keratoconus, severe dry eye, glaucoma)
Pregnancy or breastfeeding (prescription instability)
Certain medications affecting corneal healing
Corneal thickness is among the most common disqualifying factors because the procedure requires removing a precise amount of tissue to achieve the desired correction while maintaining adequate residual thickness for structural integrity. Patients with naturally thin corneas or high prescriptions that would require excessive tissue removal may not be candidates. [S1]
Prescription stability matters because laser surgery provides a permanent change to your eye's optical structure. If your prescription is still changing, the correction may not last, and you could require enhancement surgery later. Most surgeons require a stable prescription for at least 12-24 months before considering surgery. [S2]
Systemic conditions like uncontrolled diabetes or autoimmune diseases can impair healing and increase complication risks. Similarly, certain medications—particularly some acne treatments and immunosuppressants—may affect corneal healing dynamics. Pregnancy and breastfeeding cause temporary prescription changes due to fluid retention, leading most providers to recommend waiting until several months after delivery or weaning before screening.
Verifying Provider Credentials and Technology
When selecting a screening provider, verifying credentials and understanding the technology used are essential steps in protecting your health and investment. Your screening provider should use certified diagnostic equipment that meets international standards for accuracy and reliability.
Credentials to Verify
Board certification in ophthalmology for the evaluating physician
Accreditation of the facility by recognized healthcare bodies
Technology and equipment from established manufacturers
Surgeon experience with the specific procedure being evaluated
Our partner facilities have been vetted for appropriate accreditation and can provide verification documentation upon request.
Technology differences between providers can affect screening accuracy and the reliability of results. Advanced topography and tomography systems provide more detailed corneal maps than older equipment, which may be particularly important for patients with complex prescriptions or corneal irregularities. Ask your provider what technology they use and whether it aligns with standards you would expect at facilities in your home country.
Red Flags to Watch For
Pressure to commit to surgery immediately after screening
Refusal to provide itemized cost breakdowns
Inability or unwillingness to explain screening results clearly
No clear path for follow-up if you are deemed ineligible
Guaranteed outcome claims or "risk-free" language
Reluctance to provide references or patient testimonials
Understanding the technology used during screening helps you interpret your results and compare findings across providers if needed. High-quality diagnostic equipment produces consistent, reproducible measurements that your surgeon can rely on when planning your procedure.
Preparing for Your Screening Appointment
Effective preparation helps ensure accurate results and efficient use of your time, particularly when traveling internationally for evaluation. Discontinue contact lens wear before screening, as contacts can temporarily alter corneal shape—typically 2-4 weeks for soft lenses and longer for rigid gas permeable lenses. [S1]
Documents to Prepare
Current glasses or contact lens prescription history
List of all medications and supplements
Previous eye examination records (if available)
Medical history documentation
Insurance information if applicable
For medical tourists, coordinate with your provider before booking flights. Ask whether preliminary screening can be conducted remotely or through a partner provider in your home country, which might help identify obvious ineligibility factors before international travel. Confirm what technology is used for screening and ensure it meets international standards. Our Travel Coordination team can help arrange logistics for your international screening appointment.
Prepare a list of questions for your consultation. Ask who reviews your screening results—ideally, the surgeon who would perform your procedure. Inquire about the clinic's protocol if you are deemed ineligible, including any refund or credit policies. Understanding these details in advance prevents difficult decisions under time pressure.
After Screening: Results and Follow-Up
Once screening is complete, your results are typically reviewed by the surgical team to determine candidacy. This review may occur same-day or within a few business days depending on clinic workflow. If approved, you will receive a surgical recommendation and can discuss scheduling, preparation protocols, and what to expect during recovery.
Transfer Limitations
Screening results are provider-specific and generally cannot be transferred between clinics. If you complete screening abroad but later decide on a different provider, you may need repeat evaluation.
If deemed ineligible, your provider should explain the specific reason and discuss potential options. Some conditions are temporary—such as dry eye or prescription instability—and may become eligible after treatment or time. Other factors, like insufficient corneal thickness, may make alternative procedures like PRK or lens implants more appropriate than LASIK. Your screening provider should discuss these alternatives and, if appropriate, refer you to specialists for further evaluation. Learn more about Eye Treatment Options that may be available based on your candidacy. [S2]
Follow-up care after screening may vary by provider. Inquire about what happens if you need to reschedule surgery, whether any tests need repetition if significant time passes, and what support is available if you have questions about your results. Understanding the full scope of included services helps you evaluate package pricing accurately and plan for any additional costs that may arise.
Screening results typically remain valid for 3-12 months, though this varies by provider and your specific circumstances. Prescription changes, pregnancy, or new medications could affect validity. If significant time passes between screening and surgery, some tests may need repetition to ensure current accuracy.
