Tips and Tricks in Corneal Inlay Implantation and Postimplantation Cataract and Vitreoretinal Surgeries
This film provides tips and tricks to help better plan and perform the Kamra corneal inlay procedure, proficiently manipulate the inlay within the stroma, and achieve better centration. Also, surgical footage provides valuable tips performing phacoemulsification and vitreoretinal surgeries in eyes with an implanted corneal inlay.
A new treatment for presbyopia is shown in which a lenticule is created to solve presbyopia.
Multifocal IOLs have become increasingly popular with the advent of optomechanical design. Many factors must be considered when choosing one, for example: pupil dependence and light-energy distribution. Despite improved visual performance, some photic phenomena are unavoidable due to intrinsic tradeoffs. Various aspects of multifocal IOLs are reviewed to describe the design concept.
Anterior corneal scars can be addressed refractively using an excimer laser in PRK mode to result directly in unaided emmetropia. The film highlights 2 decades of experience in approaching all kinds of corneal scars irrespective of their causes using methods that result in an optically optimum anterior surface, resulting in refractive neutrality.
A 74-year-old patient was referred for the treatment of severe blunt ocular trauma with iridodialysis exceeding 200 degrees, posterior lens dislocation, and vitreous hemorrhage. A triple procedure was performed comprising phaco vitrectomy, sutureless intrascleral IOL fixation, and iridoplasty. One week after surgery, the acuity was 20/50, the cornea was clear, the IOL well centered, and the retina remained flat.
The iris is one the most frequently affected structures in blunt eye injuries, as are the lens, anterior chamber angle and zonular fibers. This film presents an adult victim of blunt ocular trauma who presented with total iridodialysis and traumatic cataract. Surgical correction of the anterior segment was performed, resulting in pseudophakia with a 4.0 mm centered pupil, somewhat reactive, but with a corrected visual acuity of 10/10.
Fundus examination of an injured, collapsed eye with a scleral trepanation and vitreous prolapse is visibly challenging. A super-wide angle fundus camera (Optos 200Tx) is used to detect nonmetallic vitreous foreign bodies in a collapsed eye. The 2 cases presented showcase the vitrectomy application for the removal of eyelashes that entered the peripheral fundus. These cases demonstrate the usefulness of the fundus camera in detecting vitreous objects.
This film demonstrates the use of laser spectroscopic studies on the anterior lens capsule to capture new information on the molecular level changes in the capsule when stained with trypan blue. The changes in the physical characteristics of the dye-stained capsule are validated, and new guidelines to select the concentration and exposure time of the dye to suite the surgeon are suggested.
Several surgical challenges and high rates of complications can be encountered in cases of persistent hyperplastic primary vitreous associated with cataract, in which fetal hyaloid vasculature fails to regress, forming a posterior fibrovascular sheath. This film demonstrates a new surgical technique for managing such cases to obtain a clear visual axis, resulting in a gratifying outcome.
