Hi, people.
Perhaps somebody remember me, I did not visit the surgicaleyes for the last 2 years. Since no remedy was available for my 4.5mm optical zones and 8mm pupils, I have choosen not to think about it for avoiding the depression I started to develop. So all this time I was living near the university campus (no need for driving...)and spend all my time in my research studies (no time for movies and night clubs...)
Nevertheless, I am back...
Please comment this article...what do you think about it?:

Retreatment to enlarge small excimer laser optical zones using combined myopic and hyperopic ablations.

PURPOSE: We describe a retreatment technique using a combination of large-diameter myopic and hyperopic excimer laser ablations of a near equivalent diopter value to enlarge previous small ablation zones without altering the refractive result obtained by the initial surgery. METHODS: Eight eyes of six patients were retreated with a Technolas Keracor 217 laser in order to enlarge the optical zone. All patients had a good refractive result after the initial surgery, but reported halos under low light conditions. Retreatment consisted of a combination of myopic and hyperopic ablations of near equivalent value, eg, -1.00 D and +1.00 D treatment. These opposite value ablations should neutralize their respective refractive effect, but by removing a larger diameter of tissue, actually displace the transition zones further toward the corneal periphery. Although the initial treatment used photorefractive keratectomy in four of the eight eyes, LASIK was used for retreatment in all eyes. Improvement was assessed subjectively by the patient and was measured objectively with a Technomed C-Scan ray-tracing program. RESULTS: In six of eight eyes, patients experienced moderate or marked improvement. This improvement was objectively correlated on postoperative corneal topography. CONCLUSION: Combined larger diameter myopic and hyperopic retreatment seems to be safe and effective for enlarging previous small treatment zones, reducing symptoms such as halos in selected patients.

Hi Pavel,
did you get the enhancement? I'm in the same position as you are... Keep me posted

Hi Mel,
I have seen your other post and I am not sure we have the same problems. You should check out what is going on there and what is the reason for your rainbow halos.
For your question: yes, I had enhancement. Actually my problems are not simple and from the beginning it was clear that 1 surgery will not be enough for major improving, so I am now after the first surgery and before the second one. It is too early to say to which degree the vision will be improved finally.
I had the surgery only after all other options failed.
I will keep posting about what is going on with my vision, but only after getting some idea myself what is going on, and this will take at least few more months

Hi Pavel,
my surgeon saw me about my rainbow halos.. but he doesn't know what's going on since my topographies are as they were before..

Anyway, when I was talking about same the same problems we share I was pointing my small ablation zone vs my pupil size.. So I am very interested in knowing if this retreatment is going to work in making a big difference.. I wish you good luck and keep me posted !
