Michael J. Wojciak, O.D.


I am an Optometrist with 25 yrs experience. I currently practice in Rolling Meadows, Illinois. I specialize in all types of contact lenses. Please forward appropriate questions pertaining to eye exams, glasses or contact lenses only. I will always attempt to be as "specific" as I can on my answers. This is often difficult when the questions do not provide enough information or visual presentation is needed. ***I will reject any question involving self-prescribing of contact lenses or involving contact lens measurements/comparisons (such as changing base curves, measurement comparisons between brands etc). Contact lenses are a medical device and need to be properly fit by your Doctor. Also in respect for patient privacy, I will not answer third party questions, unless a parent or guardian is asking a question about their child.*** I appreciate your confidence.

Something interesting about this subject that others may not know:

The new silicon-hydrogel lenses are potentially the best contact lenses available to date. They transmit much more oxygen to the eye. The fitting, measurements and performance of these lenses can not be compared to outdated material/conventional lenses.

Something controversial or provocative about this subject

I have had so many questions where patients get hung up and obsessed with their contact lens "base curve" measurement. You can not compare one brands "8.6 base curve" to the next brands "8.6 base curve". Often when a Doctor switches contact lens brands, the base curve readings will be changed. This is OK; and it happens all the time.

HI,  Even though they all seem very different.  There are similarities...primarily in the axis number.  The increase in astigmatism is normal...although 1.75 and 1.50 are a larger increase over the first

If that is your prescription pictured, you need to go to a qualified Optical Shop. The doctor  s Rx is meant to be filled by a qualified professional, not by the purchase of dept store glasses.  They will

2015-05-02 Small white dot on top of iris:

Hi Priscilla. The iris is the colored part, inside the eye. Do you mean it is on the top of th cornea, where the contact lens rests?  If you have an ulcer, it can be quite serious. And needs to be checked
