General Crystalens Questions
Regarding the light-absorbing lens [LAL]:
1. Needs repeat procedures after a few weeks to correct the refraction, therefore not for patients from out of Mumbai
2. Person needs to wear UV blocking glasses full-time outdoors till the correction is done and the refraction is set. There may be compliance issues.
3. It only treats far refraction. Near glasses are required.
4. May be too early to know how this material behaves in the eye over the next few years
Definitely not for the near future. Crystalens better on all counts

Correct. Sometimes a very fine font like reading medicine bottles labels etc, may require a fine power. Today, accomodative lenses are the best bet for those who do not want dependence on their glasses (reading and distant).
No, this lens is an artificial lens replacing the natural lens where a cataract would have developed, so no chance of that happening in future.
This also depends on the kind of refractive errors or spectacle powers one has. Usually if the powers in the cylindrical axis over -1.00 D it is not as effective as simple spherical spectacle powers. Also, for higher cylindrical powers we do not recommend this lens, but another lens which takes care of the cylindrical errors, but these are monofocal lenses where reading glasses would be mandatory.
It is with the same pre procedure anesthesia which is in the form of eye drops. There is no pain during the procedure. The post procedure discomfort just like any other procedure, varies subjectively from person to person, but is largely quite comfortable and rarely needing to take more than one analgesic tablet.
A minimum of 4-5 days is usually required as we advise not to sleep on the operated side for about 3-4 days time, hence doing first eye surgery on a Thursday and next on Tuesday is fine.
These remain similar to any other cataract procedure as the procedure steps remain more or less same. The only difference is in the category of lens itself.
Crystalens or any lens will have no effect on the glaucoma status. This condition needs to be dealt with separately. The eye pressure needs to be in control before scheduling the surgery.
The lens exchange has no effect on the eye. But since steroid eye drops are used post surgery, the IOP needs monitoring in the immediate period. In some cases where the pressure remains high inspite of eye drops and when cataract is being planned, we sometimes club a 'trabeculectomy' procedure, which is a procedure to reduce pressure in glaucoma. But this is not in general for all glaucoma cases, but more an individualized approach.
Will send you a detailed email regarding this.
In Bandra on Tuesdays and Thursdays, in Marine Drive on Mondays and Fridays, both places by Dr Anand Shroff.
This issue she has is in the cornea. The cornea is like the window of the room, the lens is somewhere inside the room. The cornea will continue to behave as it is now. Immediately post cataract, in few cases, some amount of edema or swelling in the cornea does occur and this is temporary. Otherwise the corse that her herpetic condition will take will be again separate from the lens exchange. However, when having any acute issue in the eye like herpes, she will not be 'fit' for surgery, till this settles down.
Prior to Crystalens Procedure Questions
Every patient is different and only your surgeon can
fully explain the details of your Crystalens procedure. However, the
following information may be helpful for most patients.
Just 2-3 days earlier is fine.
About a day or two is fine. Clean lids thoroughly beforehand.
Not any different from the routine. There will be an antibiotic tablet to be started the day before the procedure.
Post Crystalens Implantation
In lens exchange it is one kind of eye drop for 3 weeks, and another for 6 weeks.
Not in the usual course, but can be an added depending on symptoms. Usually the antibiotic and anti inflammatory which lasts upto 6 weeks takes care of any symptoms like dryness, redness etc. which are very temporay and can clear up in few minutes even.
Not had any cases mention this in cataracts and lens exchange, as there is no surface treatment here like in LASIK, we treat inside the eye, so because of that the surface 'feels' the same.
This again is temporary. May happen if cataract is well developed as the cataract has then started blocking light from entering the eyes. Also, in the first week, some eye drop effect which allows more light to enter the eye (as it stays dilated) also makes the eyes relatively sensitive. However, not so bad that one feels that they cannot 'bera' any light. Just that they feel more comfortable with good sunglasses.
The protective wear is more like a small plastic shield to be worn only when sleeping at night. In the day, it is more dependent on your sensitivity to light, and usually requires sunglasses outdoors.
Usually the nurse tells you to just use a wet wipe or sponge the face gently for 4-5 days.
Nothing usually happens, however, we advise not to rub eyes vigorously. You are under cover of antibiotics. But obviously, one is not advised to purposefully put water in the eyes.
15 to 20 days is fine. But some still feel eye pressure.
Usually about a week is good, but this is best answered when you visit for the post procedure check.
In Crystalens, since we use some specific eye drop to give rest to the eye, the reading or close work is asked to be avoided for about 4-5 days. TV, PC etc can be started around Day 4.
Not really with Crystalens. We have not facded this, but some amount of non clarity in the first 10 days is fine which is more at night. Again also attributed partly to the use of dilating eye drops and its long lasting effect.
No. This is not a bother.
