How Long Should You Stay In The Hospital After The Surgery? 

LASIK eye surgery is an outpatient procedure, you can leave the clinic immediately after the surgery. 

How Long Does The Treatment Take?

15 minutes per eye.

What To Avoid Before The Procedure?

Before you leave for LASIK eye surgery, it’s a good idea to inform your eye doctor about your travel and the procedure you plan on having. Your ophthalmologist may also give you a quick check-up before you leave and also offer some advice.

It’s recommended that you stop wearing contact lenses and makeup for at least a few days before going in for LASIK. Contact lenses may damage the cornea and makeup may interfere with the LASIK procedure.

 LASIK Surgery Complications

Although rare, LASIK surgery complications can appear. Patients that decide to have LASIK laser eye surgery must be careful and follow the doctor’s recommendation thoroughly in order to avoid the potential: 

• Eye infection – during the recovery period it’s recommended not to swim in the sea or ocean. If you do get an eye infection, it can be easily treated with antibiotics. 
• Corneal membrane wrinkles – if you rub your eyes, squeeze or practice contact sports you may end up with a wrinkled corneal membrane which in turn leads to decreased vision. 
• Ectasia – usually appears in 1 in 15.000 patients after LASIK surgery. 

LASIK Treatment Success Rate

LASIK is one of the most common laser eye surgeries used to correct refractive errors. Post-operatory LASIK patient reviews set the success rates between 92% and 98%. This is the reason why LASIK gained so much popularity in recent years.

It’s very important to mention that there are no known long-term side effects from LASIK surgery. It’s also worth mentioning the fact that LASIK does not guarantee perfect vision, although many patients do obtain it after a few weeks from surgery.

LASIK Eye Surgery Alternatives

While LASIK offers great results for a large number of patients, it also comes with certain requirements. Patients who are unable to undergo LASIK surgery have some alternatives available to them. Here are the best LASIK alternatives available for patients.

Wavefront Guided LASIK

Wavefront-guided LASIK uses computer imaging technology to create a 3D model of the patient’s cornea. This map is then used to program the excimer laser with more accuracy since wavefront technology provides highly precise measurements of the patient’s cornea.

This is the main reason why Wavefront-guided LASIK provides patients with better results than glasses or traditional LASIK. Not only that but this new technology has been proven to reduce post-op side effects such as contrast sensitivity and problems with night vision.

A higher percentage of patients achieve the near-perfect vision by undergoing Wavefront-guided LASIK instead of the traditional procedure.

LASEK

LASEK eye surgery uses a micro-instrument called a trephine to modify the epithelial corneal tissue, creating a flap. The alcohol solution is then applied to the area in order to further loosen the epithelial cells.

The flap is then moved aside and the rest of the procedure is comparable to PRK eye surgery – the cornea is sculpted, and the flap is repositioned before being secured in place with the help of a contact lens that will help with the healing process.

EpiLASIK

EpiLASIK uses a very small micro-keratome called an EpiKeratome to detach a small sheet of epithelial tissue from the cornea itself. The sheet is then moved to the side and the procedure continues as with PRK treatment. This thin sheet will be moved back into its place, under a contact lens that will help the healing process.

CK or Conductive Keratoplasty

Conductive Keratoplasty is a minimally invasive thermal refractive procedure that’s usually performed on patients over 40 years old. This procedure is used to treat mild or moderate cases of hyperopia.

Conductive Keratoplasty does not use a laser at all, but instead, the doctor will use a micro-probe that releases radio frequency energy, applying heat to certain portions of the cornea. The extra heat will cause the cornea to shrink and tighten, increasing its curvature and improving eyesight.

Conductive Keratoplasty can also be used to treat presbyopia in patients with fair vision but poor near focus. CK is unfortunately not a permanent solution and some patients may require further procedures.

Phakic Intraocular Lenses or IOLs

Phakic intraocular lenses are best suited for patients suffering from severe refractive errors that cannot be treated with surgery.  Phakic intraocular lenses are also called implantable contact lenses – these are placed in front of the eye’s natural lens, either in front or behind the iris. Once the lenses are inserted, the patient’s vision is corrected.

Refractive Lens Exchange or Clear Lens Extraction

Refractive Lens Exchange uses an artificial lens to replace the patient’s natural eye lens in order to improve their vision. This procedure is very similar to cataract surgery, with the addition of an artificial lens.
