LASIK surgery has gone through enormous improvements since it was first approved by the FDA in 1995. The biggest improvement was the application of wavefront technology. The preferred treatment is now Custom LASIK which uses wavefront technology to diagnose your two eyes. There are four companies that make laser systems to deliver Custom LASIK, and all are excellent.
Traditional LASIK diagnosis
In the early years of LASIK, diagnosis was done the same way it is done for your glasses prescription. You sat looking with one eye into an aperture while the eye doctor or his assistant flipped from lens to lens asking you to read the smallest line of letters you could see clearly. That floor-standing device bristling with lenses is a phoropter and is still used every day for prescribing contacts and glasses.
The early LASIK vision correction was based on the data gathered in this phoropter diagnosis. That meant that your LASIK treatment was by no means unique. A million other people had the same prescription as you did and received the same laser vision correction.
Custom LASIK diagnosis
No phoropter is used for Custom LASIK diagnosis. Instead, you sit at a wavefront machine such as the AMO / VISX WaveFront™ System. A light is shone into your eye and when it reflects back into the system it is recorded and measured. It is not the straight-beam light that went into your eye – it is now a wavy light modified by the microscopic contours of your eye.
Your eye information is expressed by the system’s computer as a 3-D colored map of your eye. It tells your LASIK surgeon what shape and pattern your two corneas have and that tells him how it needs to be changed for clearer vision.
Higher Order Aberrations
Traditional LASIK treats the three conditions of nearsightedness, farsightedness and astigmatism, putting that correction right into the eye’s cornea instead of into a pair of glasses.
· To correct nearsightedness the LASIK laser will flatten the cornea slightly
· To correct farsightedness the laser will steepen the cornea a little
· To correct astigmatism the laser will create a rounder shape instead of the more oval shape of an astigmatic cornea
Custom LASIK does that and more besides. It also corrects more subtle irregularities of the cornea known as the higher order aberrations. This is why Custom LASIK is about 25 times more precise than Traditional LASIK. Higher order aberrations are things like:
· Glare in low light conditions
· Halos around light sources
· Starburst (light scattering out from its source)
· Ghosting (faint second images creating double vision)
By correcting the minute corneal irregularities that cause these vision defects, Custom LASIK gives you improved quality of vision as well as more vision quantity. In other words, you will not only see clearly at more distances (quantity), but will see everything more clearly than you would have after a Traditional LASIK surgery (quality).

This was my custom lasik intralase surgery preformed by Dr. Daivd Schanzlin of TLC Laser Eye Center in La Jolla, California. I was at a -2.75 and -3.0 with 1.0 astigmatism . By the next day I was already seeing 20/20. There was no pain what so ever during the surgery. There was some pain and dryness later that night after the surgery but nothing out of the norm. I am experiencing slightly dry eyes but it has only been 4 days since my surgery. Im so pleased with the outcome. *The voice you hear is not the doctors but my brother’s.
Given that all humans are unique beings, their troubles will also be so. In that case if standard measures are practiced to each and every person irrespective of the problems, can there be effective solutions? No.
Likewise, Custom Lasik surgery on the eyes, as is enlightened by the term itself, caters distinctively to your individual needs and situations rather than involving the general modus operandi which was formerly used. Prior to the emergence of custom lasik surgery, many cases of postoperative barriers had appeared causing a lot of perplexity and maiming the issue. With custom lasik surgery you can rest assured that the procedure would be absolutely adapted to your eyes and its associated vision tribulations.
Though a pricey procedure, there is much compensation to undergoing custom lasik surgery. People go for it given the superior results.

Thanks TLC Laser and Dr. Tooma! I went from -4.25 to 20/20 vision. The operation was less than 10 minutes and pain free! I can now see and it was worth every dollar I payed!!
