Type III hypersensitivity is mediated by the formation of antigenâantibody complexes that either activate complement for direct toxic effects or attract inflammatory cells, especially neutrophils that bind the complexes by Fc receptors and cause tissue damage.
1 The cost of laser eye surgery, known as LASIK, varies widely from surgeon to surgeon, with a national average of about $1,950 per eye. 2  Average prices do not vary much by geographic region, but minimum and maximum fees do. 3  All About Vision provides a chart of regional cost differences. This allows for a more precise vision correction and possibly lower chances of post-surgery complications. 2  Most surgeons charge between $200 to $500 extra per eye for this. 3  Also, if your surgeon uses IntraLase, another new technology, you can expect to pay an average of $344 more per eye.
Some surgeons quote a flat fee per eye, while others quote a price based on the amount of vision correction needed or the technology being used. According to one source, the average cost overall for laser vision correction in 2013 was $2,073 per eye (up from $1,941 the previous year). The results show an average of: $2,223 per eye for laser vision correction procedures (LASIK, PRK, LASEK, etc.) at surgery centers where a single price is quoted regardless of technology or vision correction requirements.
