A refractive error is a very common eye disorder. It occurs when the eye cannot clearly focus on images. The result of refractive errors is blurred vision, which sometimes is so severe that it causes visual impairment.
The three most common refractive errors are
Myopia (nearsightedness): difficulty in seeing distant objects clearly;
Hyperopia (farsightedness): difficulty in seeing close objects clearly;
Astigmatism: distorted vision resulting from an irregularly curved cornea, the clear covering of the eyeball.
Apart from the above is the occurrence of Presbyopia, which leads to difficulty in reading or seeing at arm’s length. It differs from the other disorders in that it is linked to ageing and occurs almost universally.
Manufactured in Switzerland, the Alcon Wavelight Refractive Suite represents the most highly advanced technology. It transmits laser pulses at a considerably denser rate than other femtosecond laser equipment. For this reason, the energy used to make the flap as well as the spot size are significantly smaller than with other femtosecond-based lasers. Due to its low amount of energy, side effects and mechanical tensions on the cornea are as minimal as possible.
Contoura Vision Treatment
Contoura Vision is one of the most advanced technology in Laser Vision Correction. Apart from correcting the Specs power, Contoura vision also corrects the corneal irregularities while working on the visual axis. Hence it provides sharper visual outcomes.
The inclusion of Femtosecond lasers in refraction error surgery has raised safety to a whole new level, because the flap is no longer required to be made with a mechanical razor (blade), as was the case in the older technology represented by LASIK operations. This is an outpatient procedure and does not require hospitalization. Topical anesthetic drops are used and the patient is awake during the entire procedure. Near to normal sight capacity is restored and the patient can enjoy the results the very same day following the surgery.
How Femto-Lasik Works
The Femto LASIK surgery doesn’t require hospitalization. The eye to be operated will be anesthetized using eye drops. The surgery takes only a few minutes and doesn’t involve pain.
Benefits of Femto-Lasik can be summarized as follows
Accurate, precise and safer procedure
Painless, bladeless technique
Faster recovery period
Complications caused by cuts are avoided
Wider spectrum of refractive error correction
Those ineligible for Lasik can use FEMTO LASIK
