it depends on the patient and the doctor and the pterygium. each procedure has its pros & cons, and each procedure works a little bit differently depending on the lesion. there is no real 'better' or 'worse' procedure. too many factors.
best to trust your surgeon. if you are uncomfortable with his/her decision, seek a second opinion.
Is there a significant difference in recovery time for the two options? And, is it common for a surgeon to use just one technique, or do most perform both the "stitchless" and "stitch" autograft procedures?
most surgeons that i know do both or have done both. the stichless one has shorter recovery time, but as far as i know is limited to a certain size/type of pterygium. i think the larger/more invasive ones need the stitch type.
Thank you for your help. I appreciate your honest answers.
