Who Are Not Good Candidates for LASIK Eye Surgery
Who Are Not Good Candidates for LASIK Eye Surgery Eye health has multiple dimensions to consider, especially when contemplating options like the revolutionary LASIK eye surgery. This laser-assisted procedure offers a solution to common refractive errors such as myopia and hypermetropia, promising freedom from corrective eyewear for many.
Not everyone can benefit from this modern marvel. Certain underlying conditions and physiological states may render some individuals unsuitable candidates. For instance, certain corneal diseases or insufficient thickness of the cornea could potentially complicate outcomes post-surgery. Moreover, expectant mothers or those nursing newborns might need to postpone their plans due to hormonal changes that impact ocular stability.
Underlying Eye Conditions
Eye conditions can significantly influence the suitability of an individual for LASIK eye surgery. One such condition is keratoconus, a disorder that causes a cone-like bulge on the cornea, leading to distorted vision. While LASIK aims to correct vision by reshaping the cornea, in those with keratoconus, this procedure may
exacerbate the thinning and bulging process. This potential risk makes individuals with keratoconus unsuitable candidates for the operation.
Another prevalent eye condition is cataracts. Characterized by clouding of the lens inside your eyes, it affects light entry and impairs visual clarity. Although LASIK enhances vision by modifying corneal shape, it does not address problems associated with internal ocular structures like lenses; hence people with cataracts cannot benefit from this surgical intervention.
Glaucoma represents yet another contraindication for LASIK eye surgery due to its association with elevated intraocular pressure (IOP). Since LASIK involves creating a flap in the cornea which could potentially alter IOP measurements post-operation, diagnosing or managing glaucoma becomes challenging after undergoing this procedure.
Retinal detachment poses serious risks too when considering refractive surgeries like LASIK. The retina’s role as an integral part of our visual system means any detachment could lead to severe sight impairment or even blindness if left untreated. Given that certain surgical procedures might heighten retinal detachment chances due to intraocular pressure changes during surgery, these patients should be considered unsuitable candidates until their retinas are securely reattached.
Diseases that directly affect corneal health, such as infections or dystrophies that disrupt normal tissue structure and function, can create obstacles that make a person unfit for undergoing laser-assisted operations on their corneas, as it could risk further harm.
Pregnancy and Nursing
While LASIK eye surgery holds promise for many people, it may not be advisable for some specific groups like pregnant or nursing women. Hormonal fluctuations during pregnancy often lead to vision changes due to alterations in fluid balance and blood circulation within the body. These changes can affect corneal thickness and shape, making it challenging to accurately determine the required amount of corneal reshaping needed during LASIK.
Pregnancy often brings about dry eyes, a condition that can be exacerbated by LASIK surgery. Adequate tear production is crucial for optimal healing and visual outcomes after LASIK, and the increased risk of dry eyes during pregnancy might compromise the efficiency of the recovery process. Therefore, the hormonal shifts associated with pregnancy make expectant mothers unsuitable candidates for undergoing such procedures.
Nursing mothers are also encouraged to wait before considering LASIK eye surgery. During lactation period following childbirth, hormones continue their roller-coaster ride as they readjust back towards pre-pregnancy levels. This transitional phase can extend the impact on ocular structures noticed during gestation into postpartum periods too; hence doctors generally advise postponing refractive surgeries until breastfeeding ceases allowing hormone levels stabilize ensuring more predictable surgical results.
It’s important that these considerations aren’t seen as permanent contraindications but rather temporary precautions aimed at ensuring best possible outcomes from an elective procedure like LASIK eye surgery while minimizing potential risks involved through careful candidacy evaluation.
Insufficient Corneal Thickness
A crucial factor determining candidacy for LASIK eye surgery is corneal thickness. The procedure involves creating a flap in the top layer of the cornea, then using a laser to reshape the underlying tissue to correct vision. However, this requires an adequately thick cornea that can accommodate such alterations without compromising its integrity or function.
In cases where individuals have thinner than average corneas, undergoing LASIK eye surgery poses a risk of further thinning, potentially leading to post-LASIK ectasia. This condition involves progressive thinning and bulging of the cornea, significantly impairing vision. For such individuals, alternative refractive procedures like Photorefractive Keratectomy (PRK) or Implantable Collamer Lens (ICL) may be more suitable options that avoid the risks associated with excessive corneal thinning.
It’s important to note that “insufficient” corneal thickness doesn’t necessarily imply abnormality. The range for normal human corneal thickness varies widely. However, surgical requirements establish specific minimum thresholds to ensure the safety and efficacy of treatment outcomes. As technology advances, newer techniques are being developed that can cater to individuals traditionally deemed unsuitable due to insufficiently thick corneas, offering hope for more people seeking freedom from glasses or contacts through refractive surgeries.
This underlines why comprehensive pre-operative evaluation is so integral before embarking on any elective medical intervention like LASIK eye surgery: It helps identify potential contraindications early on thereby minimizing risk while maximizing chances for successful visual correction.

Who Are Not Good Candidates for LASIK Eye Surgery: Frequently Asked Questions
What is LASIK eye surgery and how does it work?
LASIK, or Laser-Assisted In Situ Keratomileusis, is a type of refractive surgery. It corrects common vision problems like myopia, hypermetropia and astigmatism by reshaping the cornea—the clear front part of the eye—allowing light entering the eye to be properly focused onto the retina for clearer vision.
Why might thin corneas disqualify someone from undergoing LASIK?
During LASIK procedure, a flap is created in the top layer of your cornea before using laser to reshape underlying tissue. If your corneas are thinner than average, this process could potentially thin them further leading to complications such as post-LASIK ectasia—a condition characterized by progressive thinning and bulging of cornea impairing vision.
Is there any way for individuals with keratoconus or cataracts to improve their eyesight if they can't undergo LASIK?
Yes indeed! While conditions like keratoconus or cataracts may make you an unsuitable candidate for LASIK, other procedures exist that can help improve visual acuity. For instance people with early-stage keratoconus might benefit from collagen cross-linking whereas those suffering from cataracts could consider lens replacement surgeries.
Why should pregnant women postpone considering refractive surgeries like LASIK until after childbirth and breastfeeding period?
Hormonal changes during pregnancy often lead to temporary fluctuations in your vision due changes in fluid balance and blood circulation affecting ocular structures including your corneas. Since accurate assessment of these factors is crucial for planning successful surgical outcomes - doctors typically advise waiting till hormone levels stabilize post-pregnancy before proceeding with such interventions.
