Today, there are a number of terms coined to LASIK eye surgery, such as the “blade”or “bladeless” LASIK, that may bring confusion to those who need to undergo this type of corrective procedure. No matter how medical terms are used to name it or how complicated it might sound, it is still important for any patient to be familiar and be aware of how one differs from the other, especially in terms of the procedure itself and the benefits that it can offer.
For LASIK, conventionally, it involves the use of a microkeratome (which is a kind of blade) to incise the surface of the cornea, the transparent part of the eye. This will result to the formation of a flap, which will be lifted slightly away from the central portion to expose the stroma. The correcting process takes place when the excimer laser shapes the cornea by burning some of the tissues, depending on the refractive error that needs to be corrected. The last step for LASIK is returning the flap to its original position properly where it will heal naturally in a short period of time.
People now are hearing about the bladeless LASIK, which is a more updated version of the previous one and sounding safer than the former. It is a common occurrence that patients may have second thoughts on choosing the traditional LASIK because of the presence of the blade can be associated with more discomfort, thus affecting the turnout of patients.
The common process between the traditional LASIK and the bladeless one is the creation of a thin flap from the corneal surface. The difference is that the bladeless is more efficient such that a flap is produced with more accuracy and precision resulting to a better outcome. This includes lower occurrences of post-operative complications such as irritation, dislocation of the flap, errors in flap production, and others. But it must be noted that for more optimal results, this technique must be flawlessly performed by an eye surgeon who have gained expertise through experience.
Though bladeless, this surgical operation can also present post-operative complications such as light sensitivity. Also, new innovations often come with an expensive cost. But its benefits far outweigh the extra dollars one needs to shell out.
Generally, LASIK is a safe technique for correcting anomalies of visual acuity. For patients who are contemplating to go through this surgical operation, going bladeless or not, it is a responsibility to educate one’s self and weigh the pros and cons of both types of LASIK until the patient, with the help of the eye surgeon, decides which is better. As mentioned, the results also depend on the performance of the surgeon. So, choosing the right doctor with a clean and commendable record will be very beneficial rather than selecting one, on the basis of offering a cheaper fee. If there are no other constraints and if the patient desires a more accurate procedure, then it definitely wouldn’t hurt to try the bladeless LASIK operation.
