Seven-year Follow-up of LASIK for Myopia
J Refract Surg. 2009;25:312-318.
Waldir Neira Zalentein, MD; Timo M.T. Tervo, MD and Juha M. Holopainen, MD
PURPOSE
To assess the long-term refractive results, subjective parameters, and late sequelae of LASIK.
METHODS
A retrospective follow-up study was conducted on 38 eyes of 21 patients (17 with bilateral treatment and 4 with unilateral treatment) who had LASIK surgery between 1999 and 2000. Laser ablations were done with an excimer laser (VISX Star and Star S2). Follow-up was 2 months, 2 years, and >7 years postoperatively. Uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), manifest refraction, indirect ophthalmoscopy, and wavefront analysis were measured at the last follow-up and a questionnaire was answered.
RESULTS
Postoperatively, BSCVA ≤0.0 (logMAR) was obtained in 91%, 100%, and 89% of eyes at 2 months, 2 years, and at last follow-up, respectively. Postoperative spherical equivalent refraction within ±0.50 diopters (D) was obtained in 75%, 63%, and 42% of eyes at 2 months, 2 years, and 7 to 8 years, respectively. At 2 months and 2 years, 83% of eyes were within ±1.00 D, which decreased to 42% at 7 to 8 years. Mean spherical equivalent refraction at 2 months was –0.41 D, at 2 years –0.57 D, and at 7 to 8 years continued to decrease to –1.38 D. Patient satisfaction was high—100% of patients would have LASIK again.
CONCLUSIONS
LASIK outcomes tend to shift toward undercorrection over time. Postoperative ectasia was not noted 7 to 8 years after LASIK. All patients were satisfied with the postoperative results although emmetropia was not reached.
From the full text:
Currently, 4 studies with a combined total of 206 eyes have been published on postoperative LASIK results for myopia with follow-up >5 years...
In the present study, 63% of eyes were within +/-0.50 D and 83% were within +/-1.00 D of the intended correction at 2 years. This is consistent with the results of O’Doherty et al at 5 years. However, at last follow-up 7 to 8 years postoperatively, 34% of eyes were within +/-0.50 D and 42% were within +/-1.00 D. Similar to earlier results, myopic regression of the spherical equivalent refraction was noted. At 2 months, an undercorrection of -0.41 D was found; at 2-year follow-up, a minimal myopic regression to -0.57 D was noted, which continued to regress to -1.38 D at last followup. This trend toward myopic regression was noted in all 38 eyes, but it was more pronounced in eyes with preoperative spherical equivalent refraction >6.00 D and in patients aged <30 years. These results show that although refractive results after LASIK are relatively good in the short term, they tend to decline over time. |

FDA MedWatch report: LASIK doesn't last.
http://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfMAUDE/Detail.CFM?MDRFOI__ID=1353097
| Quote: | | Lasik surgery in 2000 - experienced starburst effect immediately, along with dry eyes. My vision has recently started to rapidly regress in right eye, a small amount in left eye. Symptoms: difficulty driving at night, worsened starburst effect, trouble focusing when reading, distance vision impairment. I had to purchase glasses recently, which i was told to wear at night and for the computer. Within 2 weeks, i started having blurred vision, trouble focusing so, went back to eye doctor who informed me, my vision had worsened in my right eye in the past 2 weeks. She ordered a new lens for my glasses. |

Blurry eyes are on prize, title in sight for Parajeckas
| Quote: | | Parajeckas, head pro at Pleasant Valley CC in Sutton, underwent successful Lasik surgery to correct his vision in 1996, but he has suffered from dry eyes and cloudy vision for the last year and half to the point where it affects his balance. “It felt like there was a fog over my eyes, like a windshield defroster,” Parajeckas said. “I kept on blinking, blinking, blinking.” Parajeckas had plugs implanted in his eyes to provide moisture, but his eyes got too wet, so he had the plugs removed a couple of weeks ago. He continues to use drops to try to prevent his eyes from getting dry. “It’s been a nightmare,” he said. If the drops don’t keep his eyes moist, Parajeckas may have to wear contact lenses or eyeglasses. |
| Quote: | | Parajeckas’ vision problems bother him most when he putts. Yesterday, he putted for birdie 17 times, but made only one of them — when he hit a 9-iron from 139 yards to within two feet on No. 14. |

Not a peer reviewed article, obviously.

Lasik surgery does not necessarily mean the end to glasses
By Ivan Penn, Times Staff Writer
September 5, 2009
| Quote: | At first blush, I could hardly believe my eyes. What's the point of the surgery then?
Well, I had a chat with a couple of ophthalmologists, Dr. James Salz, of Beverly Hills, a spokesman for the American Academy of Ophthalmology and clinical professor at the University of Southern California; and Dr. Steve Updegraff, a St. Petersburg ophthalmologist who underwent the laser treatment.
Salz does not dispute Consumer Reports' findings. |

MedWatch report submitted to the FDA
http://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfMAUDE/detail.cfm?mdrfoi__id=1513527
I had lasik surgery nine years ago performed by a dr. At first it was great, i could see 20/20 if not better. However, i never felt comfortable driving at night because as a result of the surgery, i had difficulties with white signs appearing very blurry, as well as the halos and so forth. After three years, i required glasses to drive. My prescription has continued to increase, requiring me to where glasses all the time. In addition, i do not drive at night, even with the glasses, unless extremely necessary. I can not see at night - it's terrible-. |
