Any update on success rate for Chrystalens during cataract surgery?

The purpose of the toric lens is to give the best possible vision WITHOUT GLASSES. The toric IOL is extra cost. Most people choose to have spherical IOLs put in and the astigmatism after the surgery is corrected with glasses. Your father is going to need glasses for some things after surgery. If money is tight it may not be worth the extra money to correct what is a relatively small amount of astigmatism.

The subject of where to leave the eye focused without glasses after surgery has been discussed many time and you can find the discussions using the search and archives.

Respected Dr.John C Hagan,

Many thanks for your help, I really highly appreciate it.

I am not currently aware of the information but I am sure the surgeon must have recommended it for the reasons you have mentioned which I will reconfirm with him.

Also I spoke to them about the eye prescription that in the left eye it shows cylinder of -1.25 so for below -1.50cylinder is toric really required, to which they mentioned that these were the eye prescription of the eye glasses which my father is wearing by when they measured the cylinder of the left eye is -2.25 so that is why they recommended Toric IOL for the Left Eye.

About the Lens, the Doctor said that they would be able to completely correct the distance vision with putting Acrysof IQ IOL (SN60WF) in Right Eye and Acrysof TORIC IOL (SN60T) in Left Eye. Hope these Lens are good and would have good results.
(I wanted to know apart from distance vision correction, what will happen for intermediate vision and is driving considered in distance vision or intermediate vision)

Currently before surgery my father is able to read the near distance very clearly without depending on glasses but has to see from very near meaning maybe 5cms to 8cms, doctor recommended multifocal but I have gone through the patient information and feedback about them and have decided against it, so I am aware that my father will have to wear reading glasses after ther surgery.

Just for sake of understanding do Toric IOL carry potentially high risk for halos or ghosting or any problems seen in multifocal?

Looking forward for your kind reply.

Hope the surgery is a success for my father, May God Bless!

There is some information missing for your father and that is whether the astigmatism is corneal or lenticular (lens). If it's lenticular then a toric lens in either or both eyes may not be necessary as removing the lens will get rid of lenticular astigmatism, however if its the much more common corneal then a toric lens would be a good choice. So possibly the RE has lenticular and the LE corneal astigmatism. You should ask for specifics from the surgeon.

This is a new topic, so it would be best to post a new question rather than using this existing thread.  However, let me comment:

The choice of lens is really between the patient and what the eye surgeon feels most comfortable with.  A toric IOL has received very good reviews, and is now the preferred way to correct astigmatism in many cases.  Your father's doctor probably feels that the amount of astigmatism in the right eye is low enough that a standard IOL would allow good distance viewing without corrective lenses, but that the left eye, having slightly more astigmatism, would do better if the astigmatism were corrected.  Limbal relaxing incisions are another way to correct astigmatism, but since your father is opting for monofocal lenses and will undoubtedly require glasses or contacts for near vision, the toric lens would seem to make sense.  The right eye might be a candidate for a toric lens also, but it is considered a "premium" lens and thus will probably require an additional expense beyond the amount covered by your father's insurance.

Respected Dr.John C Hagan III,

My Father is going to go for cataract surgery and his eye numbers are as follows:

Glasses Right: OD-9 cylinder-0.75, axis:44 vn:0.5
Glasses Left: OS-7.75 cylinder -1.25, axis:133 vn:-

Autorefraction Right Eye: OD-7.25, cylinder -1.00, axis 39
Autorefraction Left Eye: OS-6.25, cylinder -1.25, axis 169

The Surgeon suggested to go for Acrysof IQ IOL in Right Eye, and Acrysof TORIC IOL in Left Eye.

I just wanted to know that is Toric IOL neccessarily required to correct Left Eye Cylinder of -1.25 or would you suggest getting normal Acrysof IQ IOL in the Left Eye also.

The Doctor said that they would be able to complete correct the distance vision with putting Acrysof IQ IOL in Right Eye and Acrysof TORIC IOL in Left Eye.

I would highly appreciate your kind guidance at the earliest since my father's surgery is scheduled on thursday 24th march 2011 for the right eye and on monday 28th march 2011

Crystalens are slowly improving due to technical better IOL and more experienced surgeons and patients with lower more realistic expectatons.
