Toric Implant for Irregular Astigmatism

Question: I have astigmatism which can't be corrected well with glasses or contacts. Thus the vision in my left eye is always blurry and has been for over 30 years.  Can Toric Lens Implants or a type of lens implant be used to correct my astigmatism even though I don't have cataracts?  

Answer: It sounds like you are describing irregular astigmatism-which would not correct well with any type of lens implants. You do not indicate why you have the uncorrectable astigmatism. If it is due to cornea trauma, cornea disease such as keratoconus or marginal degenerations, infection or previous surgery you need to be evaluated by a cornea specialist to have a firm diagnosis. from this it may be possible to recommend treatment options as many new treatments are available to both strengthen the cornea and correct irregular astigmatism.

LASIK after Cataract Surgery-Should I Have to Pay?

Question: I had cataract surgery for the left eye a month ago with a lens implant. However, my vision is still no better, if not worse than before surgery.  The cataract surgeon said this was due to a technical miscalculation of the lens strength and might necessitate repeating the procedure, or having the LASIKsurgeon do a correction, as I had LASIK surgery 14 years ago. ( There were no problems for the cataract surgery of my right eye from 2 years ago). My question is, should the fees for surgery correction be waived, as I already paid almost $3000 for the new lens implant which didn't achieve the goal? 

Answer: Patients who have previously had any type of corneal surgery-especially LASIK-require meticulous advanced technology imaging and calculations in order to have precise lens implant power calculations. Even in the most perfect measurement situations, there is often induced calculation error as a result of the previous LASIK surgery and corneal curvature and thickness changes that have been made. Thus, just because you had a relatively uneventful first eye cataract surgery and lens implant operation, it is still not unexpected to experience calculation difficulties. In general there are two possible surgical approaches to correct residual refractive errors when the lens implant is not providing the targeted refractive outcome-LASIK or a Lens Implant Exchange. You do not indicate whether you are overcorrected or undercorrected and we do not know whether your cornea has sufficient tissue and ocular surface health to withstand another LASIK procedure-thus you may or may not be able to have LASIK. Depending on whether your cataract surgery was otherwise uneventful, a lens implant exchange might be a better option. This will really depend on the general condition of your eye. In either case, it would be important to have a thorough examination and consultation and then follow the recommendation of your cataract surgeon. You, or your insurance, should expect to pay for either procedure. Surgery-especially in previously operated eyes-does not come with a guarantee.

Cataract Lens Implant Exchange

Question: A local cataract surgeon operated on right eye for cataract and inserted a Bausch & Lomb Lens Model PC LI61AO, length 13.00mm. Optic 6.00mm, power +22.50, to allow reading computer screen without glasses, which made my sight worse-not better.  Can is this lens be removed and if so, what kind of lens replacement should be used?

Answer: Depending on how long ago the initial cataract surgery was performed and whether there were any complications, if the position and condition of the tissue around the lens implant is healthy and intact-it might be possible to remove and exchange the lens implant. It is impossible for anyone other than your cataract surgeon-or other taking current measurements- to know what lens implant it should exchanged for as for best results it requires your initial measurements and calculations as well as the exact distance you wish to have clear vision for, calculated in the implant power along with the current refractive status.

Best Lens Implant for Severe Astigmatism

Question: What is the best replacement lens implant to correct very severe astigmatism?

Answer: The choice of which is the best lens implant to use for correcting severe astigmatism should be left entirely to your cataract surgeon. Depending on the anatomy of your eye, his or her surgical technique, the amount and orientation of the astigmatism and a number of other factors the choice is best made by the person performing the eye surgery. Lens implants are not a consumer purchase like buying tires for your car and require a high degree of professional judgment in their selection.
