To start off the new blog I have decided to post a video of the corneal suturing portion of a penetrating keratoplasty. This video will serve as a video demonstration of the techniques and principles of the following posts. I will post more videos in the future but this will demonstrate suture and needle handling in addition to the basic technique. The video is silent, without sound, the explanations will be in the following posts.
Penetrating Keratoplasty or PK can be one of the most challenging procedures for the general ophthalmologist. Like all other surgical procedures it consists of a series of steps that are unforgiving and must be completed relatively perfectly to obtain an acceptable result. Failure at any one of the steps can result in high astigmatism, spherical error and even graft failure. Completed correctly, the result can look like the example above, a clear graft with barely discernible margins, astigmatism less than one diopter and an uncorrected vision of 20/25. I am going to present a series of posts that describes how we get to this result.
I have established this blog to continue to add material and commentary on anterior segment surgery. I encourage questions from both physicians and patients and will do my best to answer them as they come in. I hope that you will find this helpful and more interactive than the static website. Suggestions, questions and comments are welcome.
