Line 5 on the eye chart to your left (20/40) is the line you need to read in order to legally drive without corrective lenses Line 8 is the familiar 20/20 line. Note that it is possible (Line 9 = 20/15) to see better than 20/20. We have grouped lines 7,8, and 9 together in our results, because this zone represents a vision level that is typically described as "excellant" by even the most discriminating of our patients. |

| Laser complications: |
|
This includes decentrations of the laser treatment, central island formation, or seriously irregular ablation patterns. Mild degrees cause little trouble, but more serious situations require sophisticated retreatment procedures. Laser complications are less common with modern, top-of-the-line lasers such as the VISX Star S4. - Reported incidence: 1.2% (myopia)1 - Hale Vision Correction 2001: < 0.002% - Hale Vision Center 2011: no reported cases since commencing Eye Tracking 2001 and CustomVue Treatments in 2002. |
| Inflammation(DLK,SOS): |
|
Inflammation is a normal reaction in any surgery, and the postoperative medications typically handle this response very easily. However, if this reaction is exaggerated, it can require more extensive therapy and rarely can affect the visual outcome. Diffuse Lamellar Keratitis (DLK), which has also been termed the "Sands of the Sahara" (SOS), due to its sandy appearance under the microscope, refers to inflammation underneath a flap. As such, it is only found after LASIK. - Reported incidence: 1% non-severe, 0.02% severe (2-4) - Hale Vision Correction: 0.02% all mild - Hale Vision Center 2003-2010 (2nd-4th generation Intralase) 0.5% all mild - Hale Vision Center 2011 (5th generation Intralase) 0.0% |
| Overcorrection: |
|
It is possible for the eye to over-respond to the calculated laser treatment. Mild cases are typically visually insignificant. However, significant overcorrection can be bothersome and require a retreatment procedure to correct the situation. - Reported incidence: 1% (5-7) - Hale Vision Correction: 0.57% - Hale Vision Center: 2003-2011(Intralase period) 0.027% |
| Keratome/Flap Complications: |
|
Creation of the corneal flap in LASIK is a crucial element in the overall process. Flap complications can include small flaps, irregularly shaped flaps, very thin flaps, button-hole flaps and an irregular treatment surface. If the abnormality is serious enough, the case must be cancelled without performing the laser treatment. After a 3-6 month healing period, a satisfactory flap can usually be created in a second attempt. - Reported incidence: 0.7-11.8% (5,6,8,9) - Hale Vision Correction: 0.18% over 8600 cases - Hale Vision Center: 2003-2011 0.025% (Intralase period) 2 aborted flaps (eye too small, etc., flap not even fully attempted (both eyes treated with surface laser with good result) |
| Epithelial Ingrowth: |
|
This is a condition in which the surface epithelial cells manage to migrate beneath the edge of the LASIK flap and invade the area known as the "interface". This is rare on primary cases and most commonly associated with retreatment procedures or traumatic dislocation of the flap. Mild cases are of no significance, but more aggressive intrusions can cause discomfort, a decrease in vision or threaten the health of the flap itself. In these more serious cases, it may be necessary to re-lift the flap and remove the cells. This is usually very successful and has no serious visual consequences. - Reported incidence: 0.6-14.7% (4, 10) - Hale Vision Correction: 0.55% Incidence of Epithelial Ingrowth rises dramatically (25-35%) 2-3 years after original bladed keratome flap creation. Blade flaps are typically no longer lifted after 2-3years. Intralase flaps are much more resistant to Ingrowth due to laser edge construction but heal so well that flap lifts are rarely attempted, or necessary, after one year. - Hale Vision Center: 2003-2011 (Intralase period) 0.038% |
| Infection: |
|
One of the serious complications of any surgical procedure is infection. This can lead to serious loss of vision. - Reported incidence: < 0.1% - Hale Vision Correction: 0% in 8600 cases - Hale Vision Center: 2003-2011 (Intralase period) 0% |
| Corneal Distortion or Thinning Requiring Corneal Transplant: |
|
Reported incidence: 0.01% Hale Vision Correction: 0% in 8600 cases Hale Vision Center: 2003-2011 (Intralase period) 0% in 7900 cases |
| Corneal Perforation: |
|
Certain keratome technology can allow the flap cut to penetrate the eye, often leading to very serious consequences. Most of this technology has been replaced. Reported incidence: < 0.01% Hale Vision Correction: 0% in 8600 cases Hale Vision Center: 2003-2011 (Intralase period) 0% in 7900 cases References: (1) Montes M, Chayet A, Gomez L, Magallanes R, Robledo N.
