Wavefront optimised laser eye surgery uses the precise curvature data information from scans of your cornea, reducing so-called spherical aberrations that can occur with non-aspheric laser refractive surgery. 64. Diabetes. While there is not surgical procedure that can guarantee that glasses will not be necessary afterward, most patients do not require glasses following surgery. Yes, although it depends on the severity of your condition. Lamellar: An adjective meaning “layered.” Lamellar corneal surgery corrects focusing errors by removing or reshaping some of the corneal layers. The following adverse events did NOT occur: corneal infiltrate or ulcer requiring treatment; corneal epithelial defect involving the keratectomy at 1 month or later; corneal edema at 1 month or later visible in the slit lamp exam; epithelium of > 1 mm2 in the interface with loss of 2 lines or more of BSCVA; lost, misplaced, or misaligned flap, or any flap/cap problems requiring surgical intervention beyond 1 month; decrease in BSCVA of > 10 letters not due to irregular astigmatism as shown by hard contact lens refraction; any complication leading to intraocular surgery; melting of the flap of > 1 mm2; uncontrolled IOP rise and retinal detachment or retinal vascular accident.

For a treatment zone with the laser below 6.0 millimeters and above 6.5 millimeters in diameter because it is unknown whether LASIK with these treatment zones is safe and effective for you. Measurements including eyeglass power, tear film production, corneal thickness, corneal topography (i.e. You take medicines that might make it harder for wounds to heal, such as Sumatriptan succinate (Imitrex®) used for migraine headaches, because it is unknown whether LASIK is safe and effective for this condition. This may result in poor vision after LASIK. In LASIK a thin hinged flap or cornea is created and lifted to one side in order to allow direct laser treatment to the deeper part of the cornea (stroma). If you are over forty and hope to avoid glasses altogether in your life, this is presently the only way to accomplish this. A patient’s vision is expected to gradually improve over the next several weeks.

II. However, it is important to say that refraction problems might improve after a second surgery, but other symptoms are usually not improved. Proper control of diabetes is also required. Sometimes, you will still need to wear contact lenses or glasses. The extremely controlled and precise Allegretto Wavelight is ideal for custom operations. The procedure is a strengthening of the cross-links of the collagen fibers to allow stability.27,28 Under topical anesthesia, the central area epithelium is removed. However, a number of international surgeons have been exploring the potential role of combined LASEK/PRK with crosslinking to improve keratoconus outcomes.

Like any surgical procedure, LASIK and PRK involve risks of unsuccessful results, complications, or serious injury, from unknown and unforeseen causes. The illustration below demonstrates the use of additional pulses to the corneal periphery in order to compensate for the energy lost through reflection. The ALCON WAVELIGHT® REFRACTIVE STATION is one of the newest generations of excimer laser technology and is the first system to receive concurrent approval for the treatment of both nearsightedness and farsightedness. Most usually begin in one of the five corneal layers and may later spread to nearby layers. Fortunately visually significant flap problems are uncommon. Epithelial ingrowth is generally the easiest entity to identify and treat, although it may occasionally be associated with other interface disorders. If you’ve ever had to wear glasses while trying to play sports you know that it can be extremely frustrating and limiting.

Afterwards, the flap is put back in place, where it covers the treated area. The eye loses its ability to change focus because of the natural aging process. It can also be used to correct night-vision problems in some patients that are caused by higher order aberrations. To do the procedure, a flap of corneal tissue is created. The eyes should be clear of injury or infection. Your Corpus Christi eye doctor will then schedule multiple follow-up visits, with each eye exam aimed at monitoring the healing process and evaluating the success of the procedure as your “new eyes” continue to adjust and settle in. Be at least 18 years old, and whose prescription has stabilized for one year.

He is one of the few LASIK surgeons in the world today who holds a doctorate degree in laser physics. To learn more about LASIK and many other laser correction procedures head over to the OptiView Vision Center website for a more comprehensive guide. The minimum age is 18 years old; if you started wearing glasses when you were very young, your prescription may be stable at 18 and so you may be suitable for treatment. To see well, all layers of the cornea must be free of any cloudy or opaque areas. Albietz JM, McLennan SG, Lenton LM.
