Advancements in Laser Eye Surgery Technology
Laser eye surgery has come a long way since its inception. The advent of technologies such as wavefront-guided LASIK and topography-guided LASIK has enhanced the precision of the procedures. These technologies allow physicians to map the eye with remarkable precision, and that allows customized vision correction with individual imperfections in the patient’s vision.
Wavefront-Guided LASIK
This is a newer form of LASIK which uses 3D maps of how the eye focuses to position the laser in shaping the cornea. It not only corrects simple refractive imperfections such as nearsightedness, farsightedness, and astigmatism but also eliminates tiny defects called higher-order aberrations which the older LASIK cannot correct.
Topography-Guided LASIK
Topography-guided LASIK is a very precise mapping of the corneal surface. It is very useful in scarred corneas as well as irregular astigmatism. It tailors the laser correction based on the unique shape of each cornea, and thus more precise results are achieved.
Risks and Safety Precautions
As with any procedure, laser eye surgery carries risk. Risks of laser eye surgery are, however, uncommon. Dry eyes, halos, glare, undercorrection and overcorrection are only a few of the most common risks. They are mostly temporary and can typically be managed by additional treatment or medication.
Reducing Risks
To minimize the dangers of laser eye surgery, extensive pre-operative examination needs to be done on the patient. This is to check the patient for suitability for the operation and whether there are any pre-existing conditions which can influence the success of the operation.
Pre- and Post-Operative Care
Success of laser eye surgery is not only dependent on the operation but also on the treatment before and after the surgery. The patients have to adhere strictly to the recommendations of their surgeons to avoid any type of complication and get the maximum effect.
Pre-Surgery
They may be asked to avoid putting on their contact lenses and opt to wear glasses for the operation. This is to ensure that their cornea, when putting on contact lenses, will shift and this would tamper with the accuracy of their corneal mapping.
Post-Surgery
Post-operative care includes the application of approved eye drops to prevent infection and inflammation, and for lubricating the eyes. Rubbing the eyes and exposure to toxic substances such as smoke and dust are also discouraged.
Comparison Between Different Laser Eye Procedures
There are now a number of types of laser eye surgery, including LASIK, PRK (photorefractive keratectomy), and SMILE (small incision lenticule extraction). They each have their pros and are performed for various sorts of refractive flaws and patient requirements.
LASIK vs. PRK
LASIK has brief recovery times and is painless, whereas PRK is appropriate for people with thin corneas and cannot be forced to have LASIK. Both have very high success rates in restoring vision.
SMIL
SMILE is the latest type of laser eye surgery and consists of making a tiny lens-shaped area of tissue in the cornea, which is then eliminated using an incredibly small incision. SMILE is less invasive than LASIK and PRK and is especially useful for treating myopia.
FAQs About Laser Eye Surgery Safety
What is the success rate of laser eye surgery?
– The success rate of laser eye treatments such as LASIK is extremely high, and the majority of the patients get 20/25 or better.
Are the results of laser eye surgery permanent?
– Yes, the cornea is changed permanently, but some patients require an aftertouch in later life.
How will I be able to tell if I’m a good candidate for laser eye surgery?
– A full eye exam from an eye doctor will determine if you are a good candidate for laser eye surgery depending on the thickness of your cornea and your overall eye health.
Is laser eye surgery painful? – Most patients experience little or no pain, as the eyes are put under anesthesia in the form of numbing drops before the operation.
