This ophthalmology textbook collects the new surgical techniques for securely fixating an intraocular lens (IOL) despite a compromised or missing capsular bag
. The 71 contributions are arranged in sections addressing capsular fixation, noncapsular fixation, intrascleral haptic fixation, anterior chamber IOL, and iris claw IOL fixation.
PowerVision's unique lens design utilizes the eye's natural accommodating response to transport fluid in the intraocular lens that is implanted in the eye's capsular bag
. While most presbyopia-correcting intraocular lenses use a multifocal design that distributes light between different focal points, PowerVision's groundbreaking fluid-based design creates a continuously variable mono-focal lens, utilizing the natural contraction of the eye's muscles.
Commercial availability of PowerVision's IOL technology will be determined following significant additional development and clinical trials of the intraocular lens, which is designed to utilise the eye's natural accommodating response to transport fluid in the intraocular lens, which is implanted in the eye's capsular bag
A posterior chamber intraocular lens (PCIOL) was implanted in the capsular bag
. On the first post-operative day, the uncorrected visual acuity was 20/20.
A clear corneal self-sealing tunnel incision was given supero-tempor or temporal depending upon the astigmatism with 2.75 mm keratome, continuous curvilinear capsulorehxis (CCC) performed, lens matter removed with phaco-aspiration and simco cannula, foldable monofocal acrylic non chromophoreintra ocular lens implanted in capsular bag
, viscoelastic removed, intracameral moxifloxacin, miochol injected and wound sealed, siedel negative with hydration, making the eye tense (tamponade effect) at the end of surgery to reduce chances of retinal detachment.
One study suggests that in micro ophthalmic eyes of infants, primary IOL implantation is controversial due to unsubtle technical difficulties of implanting an IOL of adult size in these small eyes and also they got the small-diameter capsular bag
in comparability of the IOL diameter, and post-operative complications like higher rate of Visual Axis Obscuration and refractive changes.12 Another study excluded microphthalmos (64% of respondents) for primary IOL implantation.13 Development of Secondary glaucoma after pediatric cataract surgery is an important postoperative complication.
CTR can be used only when there is no anterior or posterior--capsule tears and only when the capsular bag
Unilateral spontaneous lens absorption and dislocation of the empty capsular bag
into the anterior chamber.
After disinfection, a normal saline bag (disinfected) was used for temporary suturing of the abdominal wall around the capsule to form a capsular bag
. In general, 6-8 stitches were needed, and the capsular bag
was compressed to promote the return of the abdominal contents.
Then, viscoelastic material (1.4%) was injected into the capsular bag
, and a PCCC approximately 3.5 mm was performed followed by AV and foldable IOL implantation into the bag.
The IOL is implanted within the capsular bag
through a 3mm clear corneal, self-sealing corneal wound.
