What is LASIK, and How does LASIK work?
Laser-assisted in situ keratomileuses LASIK is a procedure that can be used to get rid of glasses or contact lenses. LASIK is the most well-known eye surgery. It is most typically used to repair visual impairments through laser refractive surgery. LASIK is a procedure that modifies the cornea and improves its functioning. LASIK is one of the most prevalent laser eye treatments that patients choose.
LASIK is a surgical technique that eliminates a person’s need for glasses or contact lenses. This treatment permanently changes the shape of the cornea, treating eye problems. As a result, it is an outpatient surgical procedure that takes around 15 minutes for each eye.
The medical professional will ask you to lie on your back before the LASIK surgery. The doctor will use standard eye drops to numb your eyes to make the surgery easier. Before the surgery, the region around the eyes will be scrubbed and sanitized. In order to help you unwind throughout the process, you might also be given a sedative.
To keep your eyelid open, your surgeon will use a tool. The doctor will then apply a ring to your eye to create suction on the cornea. At that time in the surgical operation, the patient may feel pressure and see their vision fade. After the doctor has adequately placed the ring, he will attach a unique instrument known as a microkeratome to the suction ring. The doctor will then use the microkeratome blade to form a corneal flap. This blade will cut about a quarter of the way through the cornea. Your doctor will employ computer-controlled laser pulses after removing the suction ring from the microkeratome. As a result, your cornea will be reshaped. This portion of the operation typically takes 60 seconds. The specialist will then replace your corneal flap in its original location. Your doctor will monitor the eye for several minutes to ensure good bonding. Because the cornea typically binds fast, the eye does not require additional stitching.
Following the surgery, the patient is given antibiotic drops. Medical professionals will also cover your eyes to prevent you from scratching them. These shields also help to relieve eye strain when sleeping. In addition, the doctor will provide the patient with the essential instructions to ensure the safety of the surgery.
Side-effects & safety measures-
LASIK is widely regarded as one of the safest treatments for treating a wide range of eye diseases.
LASIK has no or minor side effects. Safety precautions are essential following LASIK surgery. It helps the patient prevent damage and infection after surgery. Patients must also wear glasses following surgery to protect their eyes. Wear the eye shield, glasses, or goggles as directed by your surgeon while sleeping. Or, at the very least, for a week after the procedure. Furthermore, it is critical to relax the following surgery completely. If you relax, you can resume your daily activities without any dire consequences.
How is Contoura vision different from LASIK?
LASIK and Contoura Vision are cutting-edge methods for correcting myopia, hypermetropia, and astigmatism. Both techniques and visual outcomes differ between the two types of surgery.
Although LASIK has long been the industry standard for avoiding the need for glasses or contact lenses, Contoura Vision surgery typically produces greater visual acuity and refractive results. Contoura Vision elevates LASIK corrective surgery. The microscopic contours of the cornea are mapped using the computer-assisted topographic mapping approach known as Contoura Vision. The cornea is the clear front surface of the eye.
This treatment corrects problems with the optics and curvature of the cornea. Frequently, the root of vision issues is an irregularity in the cornea’s curvature. The visual axis of the eye is the focus of the treatment. Other LASIK techniques, in contrast, focus on the pupil.
The corneal shapes produced by the computer analysis are encoded into a specifically made laser used for this operation using Contoura Vision. A laser is used to treat the cornea in accordance with a specific treatment plan. Because every patient’s eyes are different, no two treatment plans are the same.
Light enters the eye uniformly as the cornea’s flaws are smoothed out, and the optical quality is enhanced. As a result, vision becomes sharp and clear. The method goes beyond the customary adjustments provided by spectacles. After receiving treatment with Contoura Vision, the majority of patients report seeing more clearly without glasses than they did with corrective lenses. Light-related glare and halo difficulties are also far less frequent. Watching the Contoura Vision correction in action is exciting. About 65% of the patients who received the treatment had a better correction than 6/6. Tissues also heal more quickly and with less damage. In rare cases, Contoura Vision is utilized to treat patients who have had LASIK surgery but are dissatisfied with the outcomes.
The most expensive LASIK procedure is Contoura Vision laser correction. Part of the reason is that the technology is cutting-edge and requires specific tools. However, the expense also accounts for the ophthalmologist performing the surgery’s skill and education. Only a select few ophthalmologists in India are qualified and experienced to do this treatment.
In the healthcare industry, cutting-edge technologies are developed to improve the comfort and health of patients. Because many patients cannot benefit from the technology now used in the sector, technological breakthroughs are essential. Such people either develop entirely new diseases or progress to an advanced stage and cannot be treated with the current medical and surgical systems. Surgery to remove spectacles is not exempt from these developments. Scientists are working hard to develop surgical procedures with the fewest side effects and produce the desired results. Contoura Vision surgery also referred to as topography-guided LASIK surgery, is an advanced procedure. This procedure is an improved LASIK variant that offers increased benefits to individuals who are considering surgery to remove their glasses. In addition to being successful in treating general individuals, this procedure also produces positive outcomes in patients who were ineligible for LASIK surgery because of defects in the cornea. The USFDA has given the technology permission to remove the specifications.
Topography-guided LASIK is not appropriate for all patients with vision issues. In order to decide whether the Contoura vision surgery can assist the patient in terms of improving visual clarity or correcting refractive error, the ophthalmologists will perform a thorough evaluation of eye health.
Patients who fall within the following categories are not suitable for Contoura vision surgery:
Patients who are under the age of 18 because of unstable vision. Individuals with immunodeficiency illnesses and those suffering from vascular disease cannot undergo contoura vision surgery.
Individuals with a myopia condition of more than 9.00 D and patients with brows and noses that protrude and block the reflection are considered unsuitable for the surgery.
