This patient developed a dense posterior subcapsular cataract following retinal detachment surgery. Here I demonstrate how to remove a thick epithelial layer from the posterior capsule and discuss anterior chamber depth in post-vitrectomized eyes.
An 80 yo Flomax patient with severe zonular laxity can present a number of challenges during cataract surgery. Here I demonstrate how the proper use of capsule retractors makes the case safer for the patient and easier for the surgeon.
When the goal is to implant a toric IOL in an eye with recurring bouts of uveitis, poster synechiae, an extremely shallow chamber and a previous iridectomy, a step-by-step approach is required. Here I demonstrate my approach including a pars plana vitrectomy to first deepen the anterior chamber.
After posting so many complicated cases, I thought it may be time to review my standard procedure with this one-eyed patient showing some slight macular degenerative changes. Leaving this patient myopic for better reading vision quality, my chopping technique, settings, and the benefits of vacuuming the posterior capsule are all discussed.
Endothelial protection is always important, though in a patient with severe corneal dystrophy and a shallow anterior chamber, it is even more critical. In this case, I discuss several pearls for safe removal of the nucleus in a patient with a severely compromised endothelium.
We start our 4th season with a very interesting case! My preoperative plan was to use a toric IOL in this 89 year old patient with a very dense cataract. After discovering a complete lack of zonular support, I perform a vitrectomy and change my lens choice to an AC IOL. I discuss control of the remaining astigmatism near the end of the procedure.
Ocular trauma suffered 30 years ago has left this young man with a calcified and partially resorbed cataract, advanced phacolytic glaucoma and complete absence of zonular support. Completing our 3-part
series of complicated cases, this video begins with a discussion of
the preoperative OCT image. During the procedure I discuss its formidable challenges and explain the methods necessary to remove the extremely rigid lens.
Continuing with complicated cases, this month I demonstrate removal of a dense cataract in an eye with zonular laxity and a possible preexisting posterior capsule defect. Techniques employed include hydrodelineation, insertion of capsule retractors, and insertion of a capsular tension ring.
We will finish up our year with 3 rather complex cases. This month, our 57 year old patient is extremely anxious about having cataract surgery. She had uveitis and glaucoma in childhood for which a nasal thermal sclerectomy was performed at the age of 8. She subsequently developed a cataract, but opted to postpone surgery until the lens had become quite dense. She has a low endothelial cell count, possibly as a result of prior uveitis and/or intraocular surgery. Because of patient movement during the early stages of the procedure, we use tape to restrain head movement and I deliver a retrobulbar block to improve her ability to remain stationary.
We change it up a bit this month by showing 2 implantations of a stent into the trabecular meshwork in eyes with glaucoma. The first case shows a straightforward insertion, and the second demonstrates successful insertion after failure of the initial attempt.
The cataract and IOL insertion of each case were routine, so we present only the MIGS portion of each case.
