A small posterior capsule opening is converted to a posterior capsulorhexis in an eye with pseudoexfoliation, lax zonule and infusion misdirection syndrome.
During cataract extraction on an eye with pseudoexfoliation, a poorly dilating pupil, glaucoma and astigmatism, the nasal region of the zonule suddenly fails, enabling vitreous to prolapse through the zonule deshiscence. The use of capsule retractors, a sulcus fixated IOL with optic capture, 2 trabecular microstents and a pair of limbal relaxing incisions are demonstrated during this complex procedure.
A patient with a potentially problematic degree of corneal coma undergoes cataract–implant surgery with insertion of a diffractive multifocal IOL. Strategies to reduce possible postoperative glare/halo are presented and discussed.
A moderately dense nuclear cataract is removed by phacoemulsification, utilizing techniques that minimize stress on the lens zonule.
A post-traumatic pupil deformation has caused disabling glare. Two months after complex
cataract-IOL surgery with suturing of a capsular tension ring to the sclera and toric IOL insertion, the pupil is
repaired (sutured iridoplasty).
Blunt trauma has caused a subluxated cataract with vitreous
prolapse. Phacoemulsification with insertion of 2 capsule tension rings, one of them sutured to the sclera, are demonstrated.
After routine phacoemulsification and IOL insertion, a spontaneous opening in the posterior capsule is observed without obvious cause. A small capsulorhexis must then be enlarged to permit reverse capture of the optic of the single piece, trifocal IOL.
A patient with glaucoma and previous LASIK undergoes implantation of recently modified trabecular microstents after cataract extraction with IOL implantation. Stent implantation technique, post-refractive surgery IOL calculation methods, and persistent leakage from the clear corneal incision caused by the “flipped lip syndrome” are demonstrated and discussed.
Phacoemulsification of a mature, white cataract is performed. The morphology of the anterior capsule (flat vs convex) and its impact on the capsulorhexis procedure are discussed.
Methods to reduce endothelial trauma, deal with a floppy iris, and determine IOL power in a keratoconic eye with a shallow chamber and floppy iris are presented.
