Mono vs Multifocal Cataract
by amb 51, Apr 13, 2007 12:00AM
Have cataract in one eye, moderate vision with astigmatism other eye. Optometrist suggests monofocal lens, Opthamologist pushing ReZoom lens.
Concerned about halos and glare. Wearing glasses is not as issue. I read a lot, work involves computer, commuter driving.
If get monofocal or multifocal lens, what if other eye eventually gets a cataract.

Opthamologist said to get ReZoom since other eye will most likely also develop a cataract.
My Mother has standard lens which have been used years, was done 3 years ago, they are set for just distance, says very little glare at night, everything from arms lenght out is very clear vision, needs glasses to read a news paper size print, but, can read some without glasses.
Myself, I need Distance, Night Driving, and Intermidiate distance.
I will choose a single focal lens, both set for distance, with one set slightly stronger to hopfully clear up the intermiate vision, and using reading glasses will be a small trade off , to be able to drive a night.( I had mono when I had Lasik done, set for distance and reading, there was always a strong pull from one of the eyes, looking at a distance , right pulled, reading the left eye pulled, did not like that constant pulling feeling, went back,adjusted right for distance, pulling was gone. following is some info from different sources that I copied and pasted in word pad, trying to gather as much info as possible in one place, lens I have been looking at
( Tecnis, B&L AO, Acrysof IQ )
These are a new generation of lens implants, which are wavefront-adjusted to your eye. They generally give sharper, crisper vision and usually better night vision
Patients who have the most to gain from aspheric lenses are those who have undergone myopic refractive surgery, according to Asim Piracha, MD, who is in private practice at the John Kenyon Eye Center with offices in Jefferson, Ind., and Louisville, Ky. “The patients who would do the worst with these lenses are those who have very steep corneas, such as keratoconus patients, or those who have had previous hyperopic refractive surgery
noting that while it is not yet standard practice, “the best way to choose an aspheric IOL for a particular patient is to measure the patient’s preoperative corneal spherical aberration.” Dr. Nichamin is the medical director of the Laurel Eye Clinic, Brookville, Pa.
For example, a patient with +0.27 µm of corneal spherical aberration may be a good candidate for the Tecnis lens, while patients with very little spherical aberration may do better with the SofPort AO lens. The AcrySof IQ lens could be considered for some patients who fall somewhere in between.
I have not found these lens mentioned in these forums, except one fellow had the sofport AO, and says he is very pleased with the outcome, just putting something else here to consider, there is much more info like this on the web
All 3 lens seem to be doing equally well, just a matter of which would best suit the individual
As long as the surgury goes well, any type of lens seem to give good distance and intermiate, the multifocal, just does not seem to cut it for night driving
I hope this might help others, BEST OF LUCK TO US ALL
My doctor recommends ReSTOR lenses if I go with multifocal, but reading some of the accounts at the medhelp forum at http://www.medhelp.org/forums/EyeCare/messages/353.html gives me concern. Have the lenses improved in the last year or so?
If I go with monofocal distant, what is the depth of field like? I know I will not be able to thread needles, but will I be able to work at a computer without glasses? (I spend a lot of time reading and working at a laptop computer). I have used glasses since I was a child, so am used to them.
The aspheric IOL are new as well, have not found much about them, from people who have them, I have read some studies on the Internet about them, studies claim they give more contrast sensitivity, a quote " What we found was nothing short of amazing. This study showed that the Tecnis lens improved contrast perception by 38.5 percent during the day and by 100 percent at night" Night driving is important to me, will do what I can not to give it up,
I know I will go with a standard lens or an aspheric IOL, DO NOT KNOW WHICH YET, want to try to keep the intermediate distance for work and computer, hopefully making one lens a little stronger will do this, and not give me the pulling feeling the mono vision gave me when I had Lasik done. GLASSES for reading, or progressive lens for reading and computer, whats the big sacrifice with that ? almost everyone over 50 years old has them, THERE IS NO GIVE IT ALL BACK LENS YET !
IF you find a give it all back lens, please let me know, I want one to !
