An evaluation of the final "sutures out" postoperative astigmatism in two groups of keratoconus patients undergoing penetrating keratoplasty is presented. Group I consists of a retrospective evaluation of keratoconus patients who underwent penetratin

Two of the major factors affecting the amount of astigmatism correction are the length of the transverse incision and its distance from the center of the cornea. Many nomograms used in clinical practice have been created by varying the length or clea

The surgical treatment of excessive myopia following penetrating keratoplasty has been largely ignored. Oversized corneal grafts can induce myopia and the Troutman wedge (block) resection has been used to correct astigmatism by removing tissue in a s

Many studies of radial keratotomy have been performed, however quantitative laboratory evaluation of the biomechanics of this procedure is still incomplete. Furthermore, most measurements of strain in the past have utilized strip testing, thus destro

A simple technique involving additional compression sutures and the use of a subjective operating keratometer is described for use in managing excessive astigmatism following suturing for penetrating corneal trauma. By minimizing "sutures in" astigma

As refractive procedures involving the cornea have proliferated, concerns over the long-term stability and predictability of these procedures have occupied a more prominent role.Procedures and principles of mechanical engineering to mathematically mo

Since the introduction of radial keratotomy, accurate incision depth has been difficult to achieve with any corneal knife. To assure repeatable depth of incisions and to adjust the refractive effect of these incisions after the surgery, I have develo

The problem of astigmatism, occurring both congenitally and in conjunction with cataract and refractive surgery, is a common and significant one. A review of patients in this study shows 18% greater than 2 diopters and 6% greater than 3 diopters of a

A common peripheral abnormality, which I call "microdehiscence," can in some cases cause the progressive central astigmatism that commonly follows penetrating keratoplasty. The results of a small clinical study show that placing additional suture(s)
