Does anyone have any information on pinhole contacts.
Thanks Lisa |

does anyone have any information on a DR who has experience fitting rgp's in Michigan, indaina, or illinois. I have z-waves but they do not help the contrast sensitivity loss, they do help a little bit with the starbursts.
Thanks, lisa |

Pinhole contacts will not only look funny (large black pupil look), but supply little light and make contrast sensitivity worse.

What you are really wanting is a wavefront generated lens as this will allow for improved quality of optics. I can't tell you if they are marketed yet, I have seen press releases and advertising blurb though.

Grant,
Are wavefront contacts soft or hard lenses? Could a wavefront lens increase the power of correction out toward the periphery for those of us with large pupils and little to no correction on the outer edges after lasik? A soft lens that has varying degrees of correction like a backwards blend almost (to counteract the lasik blend). Probably just wishful thinking, but maybe you could offer input. |

I HAVE SEEN A FEW LABS ADVERTISING WAVEFRONT LENSES, BUT AM A BIT PUZZLED ABOUT IT AT THIS STAGE. a WAVEFRONT LENS NEEDS TO BE TAILORED SPECIFICALLY, AND NOT MANY OPTOMS HAVE THE EQUIPMENT. aLSO THERE IS A PROBLEM WITH POST-rs AS THIS NEEDS A RESERSE GEOMETRY REAR CURVE AS WELL AS WAVEFRONT GENERATED FRONT.
TO DATE I HAVE NOT SEEN ANYTHING WORKING. |

All,
The term "WAVE", as in zWAVE or WAVE RGPs, does not have any connection to the term "Wavefront ". For the RGPs, the term "WAVE" refers to a lens fitting theory which describes how the backside shape is developed to be able to be produced on a computer-controlled lathe, creating a shape which is smooth and comfortable to the wearer, while conforming to the shape of the patient's cornea. For more information, see: www.wavecontactlenses.com For an on-line list of providers, see: www.visionrestored.com zWave lenses are available as soft lenses. When any post-refractive surgery patient is considering custom lenses, I would strongly advise having a detailed discussion with the doctor who is developing the lenses, to make sure he/she understands your problems and priorities. The lens design systems are only partially automated, and there is great flexibility for the OD to make adjustments to the lens design for fit and for correction. I talked for over an hour with my OD before he began the design process for my WAVE lenses, to make sure he understood that my worst problem was dim room/night vision. He was able to adjust the lens design parameters to increase the size of the central optical zone of the lenses, which gave me the improvements I was seeking. All too often, we walk into a doctor's office (any type of doctor) and expect him/her to read our minds and figure out how to best help us based on a 10 - minute conversation in the office. We need tocommunicate our needs and priorities if they are going to be able to provide us with the optimum solution. Good luck, Lynne |

i don't have contrast sensitivity problems. might pinhole contacts help with GASH if i have large pupils and higher order aberrations? i may be able to tolerate other side effects if they can get rid of those GD HOA's. i don't care about appearance. thanks.

RGPs in general, when well-fitted, will reduce GASH. Pinhole contact lenses will, overall, significantly reduce the amount of light entering the pupil. This would prove to reduce vision, particularly in low light situaitions.

helmit,
You mentioned that you do not have a contrast sensitivity problem, did you have medical tests for that? I actually do not feel contrast sensitivity problem (I do feel ghosting, starbursts and halos), but medical checkups show significant contrast sensitivity problems... This message has been edited.

Pavel,
no i have not had medical testing for contrast sensitivity that i am aware of. they may have checked and not told me, just like they didn't tell me i was nearsighted in one eye after surgery. thanks for asking. maybe i will ask them. i just have big horrible glare bubbles everywhere, which i have been told are "higher order aberrations" and "coma."  Dr. Hartzok, what do you mean when you say that pinhole contacts will "reduce vision"? thanks helmit |

Lynne - yours is an old Message, so i hope you are still viewing. Do you still wear z-wave soft lenses are they still proving sucessful for symptoms and comfort. It has taken until now for me to realise that wearing any contact lens provides the occular surface change I need to overcome dim vision problems however I cannot get a lens I can tolerate.
Tried several bandange - flexi 55 - proclear - night and day purevision - extreme h20 - Now wondering if a wave soft lens may be more tolerable. Any knowledge where and if these are available in the UK? Extremely appreciate any knowledge you can offer Debbie (UK) |
