LASIK – LASER ASSISTED IN SITU KERATOMILEUSIS
All of our LASIK procedures are Blade-Free. The Blade-Free experience provides an unprecedented level of safety, precision and comfort. The Ziemer femtosecond technology utilizes tiny pulses of laser light, a quadrillionth of a second each, to create the corneal flap. Each pulse passes harmlessly through the outer portion of your cornea to form a uniform layer of microscopic bubbles just beneath the surface. This bubble layer creates a flap of precise size and location. At InSight Vision Group, we utilize the Allegretto laser system which uses Wavefront- Optimized technology to automatically compensate for the curvature of your cornea. This technology is vital in elimination of glare and night vision problems that are associated with older generation lasers. Unlike older lasers, the Allegretto is capable of treating higher prescriptions and astigmatism giving you the best visual outcome.
PRK – PHOTOREFRACTIVE KERATECTOMY
Photorefractive Keratectomy, or commonly known as PRK, is a laser eye surgery that pre-dates LASIK. In both cases, a laser is used to correct any refractive issues on the corneal surface. The difference between PRK and LASIK is in how the cornea is accessed. LASIK creates a thin flap on the surface of the cornea while with PRK the outer layer of the cornea is removed in its entirety, making it a “flap free” procedure. PRK is a popular option when a patient’s cornea is especially thin, irregular, or for patients who have previously undergone LASIK surgery. The results of PRK and LASIK treatment are virtually the same. However, it should be noted that PRK procedures have a longer recovery time than LASIK.
ICL – IMPLANTABLE COLLAMER LENS
The Visian ICL is a phakic intraocular lens (IOL) used during refractive surgery for correcting myopia (nearsightedness). Unlike IOLs, which are used during cataract surgery, the Visian ICL does not replace the eye’s natural lens. Instead, the ICL is placed between the iris and the natural lens to allow the ICL lens to work with your natural optical system and allow light to better focus on the retina. Because the phakic IOL does not replace the lens, but supplements it like a prescription contact lens on the surface of the eye; it is sometimes referred to as an implantable contact lens.
If you are a good candidate we can create monovision for you. Monovision is the process of correcting your dominant eye for distance vision and your non-dominant eye for near vision. We ask that you try monovision with contact lenses prior to making the commitment with surgery. This can be done with your Optometrist or here in our clinic.
Phakic intraocular lenses (Phakic IOLs) are artificial lens implants (similar to IOLs used in cataract surgery) that are placed inside the eye. With a Phakic IOL, the patient’s natural lens remains in place. Essentially, the lens implant takes the place of a glasses or contact lens correction so as to improve the vision at distance. Patients who would benefit from a Phakic intraocular lens implant are those who have a strong glasses prescription or thin corneas, and for those who prefer a non-laser vision correction.
Using a local anesthetic, the surgeon creates a small incision in the eye and inserts the lens using specialized instruments. The exact technique and placement of the implant will differ depending on the type of lens implant chosen. Such lens implants can be removed later in life if needed or desired, and do not by design thin or change the corneal structure or integrity.
Is a Phakic IOL the Right Choice?
Individuals who are nearsighted can obtain much better uncorrected distance vision with a Phakic IOL (with their own natural lens doing the focusing for near and reading). The lens implant merely takes over the function of glasses or contact lenses for distance, and the implant is a permanent solution for seeing at distance with a minimum correction. As such, people who play sports, ski, or otherwise perform activities where contact lenses or glasses are hindrances really enjoy the vision from an IOL.
After 40 years of age, everyone’s natural lens inside the eye loses its ability to focus up close, so that reading glasses are needed regardless of the use of a Phakic IOL; in the future we may someday have Phakic lens implants that are “bifocal” in nature.
An individual is likely a good candidate for Phakic IOL if they have:
- Extreme to moderate nearsightedness
- Thin corneas and are not a LASIK candidate
- A significant history of dry eye
- A preference for a procedure that does not thin or change the cornea
Corneal Collagen Cross-Linking is a relatively pain free procedure that is performed to slow or stop the progression of Keratoconus. Currently, there is not a cure for Keratoconus, however Cross-Linking slows or halts the progression of the disease to prevent the cornea from becoming more irregular. We use special eye drops and an advanced form of UV light to strengthen your cornea.
Patients that are good candidates for Cross-Linking:
- Have been diagnosed with worsening Keratoconus or Ectasia
- Do not have cornea scarring
- Do not have too thin, steep or flat corneas
- Are not pregnant or breastfeeding
Based on study results of over a decade, it appears that the strengthening effects may be permanent. The procedure normally takes 45 minutes and you will be in our center for approximately 2 hours on the day of your procedure. Although Cross-Linking is broadly approved outside of the United States and has been since 2007, it is currently under study status in the United States and is not yet FDA approved. When Cross-Linking is performed in the U. S., it is either part of an FDA trial or is done with an off-label status. Off-label refers to a procedure or device that is performed at the discretion of the surgeon and with the full consent of the patient, including a comprehensive discussion of risks, benefits and alternatives to the proposed treatment.
