WebOptic capture pushes the IOL optic behind the world of tilted sulcus or lenticular bag planes making them a good option in these cases. To confirm an adequate capture, the membrane/capsule (behind which the optic is captured) can be nudged with a sinskey blunt hook or viscoelastic cannula just before hydrating the side incision and closing the surgery.

WebMore recent studies have shown that the improved optical designs and materials have made secondary IOL implantation a generally safe and effective procedure. 6 Secondary IOLs may be used successfully for the correction of residual ametropia, 7–9 including astigmatism, 10–13 though with some toric lens designs rotational stability has been … Web17 jan. 2015 · Additionally, the spheric shape of the IOL optic itself was shown to lead to unwanted aberrations reducing retinal image quality. 7 Furthermore, it has been found that especially IOL tilt induces coma-like HOAs. 8 Given these results and the growing acceptance of refractive surgery, visual quality after cataract surgery was a growing …
WebThis IOL is also designed with an intermediary 4.5 mm diffractive zone, making its performance less dependent on pupil size. 15 Various reports studied the performance of the lens, whether separately 16 – 20 or in comparison with other lenses. 11, 21 – 26 Objective and subjective assessments were included. 11, 15 – 26. Web25 apr. 2024 · The entire IOL including the haptics and the optic can be placed in the ciliary sulcus. Alternatively, we can do some type of optic capture through the capsulorrhexis such as keeping the haptics in the sulcus while pushing the optic posteriorly through the capsulorrhexis, or the reverse.
An Intraocular lens (IOL) is a lens implanted in the eye as part of a treatment for cataracts or myopia. If the natural lens is left in the eye, the IOL is known as phakic, otherwise it is a pseudophakic, or false lens.
