Cataract Surgery
Looks like it's time to get my cataracts fixed. There's been a small
one in my right eye for five or six years and nothing in the left. In the last six months vision in my right has gone down the tubes. The doctor says I now have three in the right eye and the left is almost ready too. I've been nearsighted (-5.5/-3.5) all my life. Any suggestins for the implant? Implant for distance and do reading glasses, or stay nearsighted and do distance lenses? My first impulse is to go for distance since I would still need safety glasses for most of what I do. Of course the glasses will come from Zenni 8 |

You see multiple superimposed images of the world, each focused at a different distance. Of course, and this what they will try not to tell you, you also see just as many multiple superimposed UNfocused images. The idea is that your perception can sort out the focused and unfocused information and selectively perceiving the focused information and ignoring the unfocused. This is kind of like seeing through a cataract to start with, where you have a focused image but superimposed with a hazy glare, and you try to make the best of it. Thus the multi-focal principle sacrifices acuity for convenience. One also has to be skeptical as these are patented products being heavily promoted at a multiple of the price of conventional IOLs. |

If you look straight ahead, they work just fine. If you use any of your peripheral vision, turn your head at all, move around, change focus a lot, or drive, they suck the big one. 80% of the lens is totally uncorrected. I fought them for two weeks and made the optical office make REAL bifocals for me. Varilux?

She has distance with glassess for computer and reading (bifocals). She seems very happy. Moreover, she is very glad she had the surgery when she did. Good luck. -- Michael Koblic, Campbell River, BC |

Discuss the variable lens implants with your surgeon. They're not variable. They're multifocal. It is a holographic lens with two fixed focal points. This is a genuinely novel device in optics, whether or not it is a good thing for an implant. Think of a Fresnel lens where the alternate rings focus at alternate focal points instead of the same focal point. This is unlike any other lens made by forming a simple curved surface. 1.25x for the computer ... That's 1.25D, not x. The number is the power in diopters. It's not a magnification. |

Any suggestins for the implant? Implant for distance and do reading glasses, or stay nearsighted and do distance lenses? My first impulse is to go for distance since I would still need safety glasses for most of what I do. Of course the glasses will come from Zenni �8 Kabow I had cataract surgery a few years ago. One eye one week and the other eye a few weeks later. All went well. Start by asking around everywhere you are able to until you find a doctors name coming up regularly. Ask older folks as cataract surgery is an old folks thing. There is probably a web site for this and where I live in Tucson there are lots of both newspaper and TV ads from lots of doctors who do cataract surgery. Keep up the asking until you get results. In my own case I found that my left eye was seeing yellow al the time. When looking at the stars my left eye twinkled and my right eye was fine. The headlights on the car were yellow. So have your eyes examined as often as needed to be sure you have determined the exact difficulties or symptons. Don't skimp on examinations. Repeat as necessary. Be sure to know exactly what is wrong. I never needed any glasses but for reading and closeup. I have the generic implants and the doctor never considered anything else. When I visited his place the nurse showed me throughout the building. Answered all may questions and invited me to return for more visits before making up my mind. In my case the recommendations for the doctor were 99%. I am sure there are others as competent but his personality meshed with mine and I went with him. Took me a few weeks to schedule the first eye and after that all went as planned. Be sure to have someone to drive you home after each surgery. I did not drive for a week after each surgery. I do tend to be more cautious than most but I did not want to have any future liability problems. Write back if you would like. and the doctor |

My first impulse is to go for distance since I would still need safety glasses for most of what I do. I had both eyes done 4 & 5 years back. I went with distance, and transition lens, (no-line) bifocal. Same reason, I wear safety glasses much of the time. I'm happy with my choice. Machinist by day, cobbler at night. Wish my woodworking skills were as good as my machining skills are. |

Living in a very rural area we were unable to find anyone who was familiar with them. She opted for reading glasses as well. It turned out well: She just got her new drivers license, with- out any eyeglass restriction, for the first time in her life. dennis in nca |
