CONSENT FOR PHOTOTHERAPEUTIC KERATECTOMY
Dr. __________________________ has described to me a procedure called Phototherapeutic Keratectomy (PTK). PTK is done by using the Excimer Laser. The Excimer Laser is used to remove scars, smooth the sur- face of the cornea, treat cornea erosions or change the shape of a cornea that has been distorted by injury 
or surgery. PTK removes the diseased portion of the cornea. This hopefully will improve vision and comfort of the eye. 
PTK lasts anywhere from ten (10) seconds to five (5) minutes. I will be given a topical anesthetic to help ensure that there will be little or no discomfort during the procedure. 
Dr. ________________________ will put medication in the treated eye and cover it with a contact lens. Following the procedure, there may be some degree of eye pain for a day or two, requiring medication pre- scribed by Dr. ________________________. I understand that I must be examined closely to assure prop- er healing of the treated eye.
Benefits: Benefits can include: Relief of pain or restoration of visual function. The benefits of PTK cannot be guaranteed. It is possible the procedure will be of no benefit and may be harmful.
Alternatives: Alternatives include: Living with my current condition, contact lenses, stromal punctures, or selection of another surgical procedure such as a corneal transplant.
Complications and Risks:  I  understand  that  my  vision  may  be  made  worse  by  this  procedure. Complications could include: Loss of sharp vision, increased corneal scarring, increased night glare or corneal infection. Any pre-existing viral infections may reappear with the use of post-operative drops. If the cornea has extensive scars, it is possible that a corneal perforation may occur that could produce other changes such as infections, cataracts or the need for additional surgery. I understand that I must be exam- ined closely to assure proper healing of the treated eye.
I understand that I may choose to live with the limitations and symptoms caused by my condition, _______________________________, and that other surgical alternatives may be available to me. I further understand that the nature of corneal scars and irregularities are so diverse that it is not possible to discuss  all possibilities in detail on this form. I have, however, discussed with Dr. ________________________ the alternatives that may be available.
PATIENT CONSENT
In giving my permission for excimer laser surgery, I have been advised by Dr. __________________ and understand the items listed below:
1. The surgical removal of the superficial layers of my cornea using the excimer laser has been elected by me as an alternative to other forms of corneal surgery.
2. As with all surgery, I understand the results cannot by guaranteed.
3. I understand Phototherapeutic Keratectomy (PTK) with the excimer laser may increase my need for glass- es and may require the use of corrective lenses to achieve my best vision.
4. I understand that although sharper vision and less glare are anticipated, it is possible that glare and clar- ity may be made worse following this procedure.
Please initial after reading this page ________________ 

5. I understand that for those severe corneal problems, where the surgical option for me is a corneal trans- plant, excimer laser PTK may not eliminate the need for a corneal transplant.
6. I understand it is impossible to state every possible complication that may occur as a result of this surgi- cal procedure.
7. I understand that not all the beneficial effects of PTK are currently known.
8. I also understand that all the risks and complications are not known.
9. I acknowledge this disclosure of information has been made to me and that all my questions have been answered to my satisfaction by Dr. __________________________.
10. I have read this form (or it has been read to me) and I fully understand the complications, risks and ben-efits that can result from PTK Surgery. I realize there are no guarantees with PTK Surgery.
I still however elect to have PTK laser treatment.
