Lasek continues to be proven over its 23 years of existence. Over 36,000,000 LASIK procedures happen to be performed around the world, and nobody has lost a watch from having the procedure. The risk related to lasek is under that associated with contacts, so that as far as infection goes, it represents a small one-time risk, as opposed to the ongoing chance of infection with contacts.
Laser eye surgerys safety continues to be attempted and assessed by government and military organisations like the US Navy, the Australian Army, and NASA. Their investigations reveal that blade-free LASIK (ie. developing a corneal flap with a femtosecond laser) is protected and approved for that SAS, Top Gun pilots and NASA astronauts.
Professional sportspeople also have used laser eye surgery to make sure their best performance on the field. Including sportspeople such as Padraig harrington and David Beckham, whose vision correction procedures undoubtedly allows them to perform at their peak.
Even with this kind of exceptional safety profile however, lasek continues to be surgery, and for that reason will invariably have the possibility for complications. Such complications are generally rare and try to manageable though, which I will discuss below.
Enhancement:
LASIK surgery is performed on the eye, a natural tissue. Although the procedure is extremely accurate, there is an average 3-4% risk the correction will be decent although not absolutely optimal. In these cases, I usually wait around A few months to ensure the stability of the residual glasses prescription, then lift exactly the same corneal flap created earlier to "fine tune" the procedures outcome. These enhancements are minor corrections, and are therefore more accurate. An excellent benefit of lasek is the fact that, although highly stable in the long run, should anyone experience any refraction transfer of their vision, enhancements like these can be at just about any amount of time in the near future.

Chance of infection:
As ive already explained, the rate of infection due to laser eye surgery procedures is extremely low, far less than infections caused by contact lenses. Corneal scarring resulting from infection occurs less than this, at a rate of less than One in 20,000. Of course this occurs, its correctible with a corneal transplant. Like a corneal subspecialist, Ive performed a lot of corneal transplants, but have not had to do one because of this.
Corneal flap issues:
Blade LASIK introduced the chance of creating an abnormal flap (like a buttonhole flap). However, blade-free (femtosecond laser) LASIK eliminates this risk altogether, and for this reason enhanced safety, it is the only form of lasek I perform.
With blade-free lasek, inflammation under the flap can sometimes occur (this is known as diffuse lamellar keratitis), and may be managed by an increase in anti-inflammatory eye drops. If cells around the cornea grow (epithelium - a very rare occurence), theyll generally absorb and disappear. When they ever proliferate, the flap can be lifted and the offending cells removed.
Dry Eye:
Temporary dry eye phenomenon is made once the nerves from the cornea are cut, which occurs during lasek. It can take about A few months for these nerves to regenerate. During this time Id advise replenishing the tear film with lubricating drops.
Ectasia:
Ectasia is fortunately a really rare occurrence in which laser vision correction causes the cornea to become too pliable, and therefore bulges forward over time. Extreme cases of ectasia have been corrected by corneal transplantation, however fortunately pre-operative screening of patients has increased in accuracy, meaning candidates unsuitable for laser eye surgery are nearly always identified before the procedure. Recent advances within the manner of collagen cross-linking also permits us to stop this rare complication from progressing further, and lets the patient maintain their vision while avoiding a cornea transplant. I am one of few eye surgeons in Australia whos experienced within this and may perform it in my surgery, however I havent needed to perform it on my own patients.

Glaring and Halos:
After the procedure, patients sometimes see starbursts or halos around lights in the night. This is usually due to the corneal flap dehydrating and stabilising, which is rare to determine this phenomenon persist longer than in regards to a week.
Quality of vision:
The majority of patients believe their vision after laser eye surgery is preferable to their vision with glasses or contacts before the operation. There is always a very small minority who experience visual quality less crisp than their pre-operative vision, but this case is generally rectified by laser enhancement.
Laser eye surgerys proven and maintained history of safety, accuracy and efficiency make it the clear strategy to becoming independent from contacts or glasses. Recent advances in blade-free femtosecond LASIK takes this to new levels, and surely represents the peak of eye surgery and vision correction.
