ANTERIOR CORNEAL TOPOGRAPHY
Italian researchers looked at changes in anterior corneal topography following femtosecond incisions. They compared these with the effects of incisions created with disposable knives. Although the slight corneal changes were comparable to those created with a keratome, they observed local topographical differences in the form of higher steepening in the region of incisions performed with the knife.

CORNEAL INCISIONS- UNDER THE MICROSCOPE
How do femtosecond and standard incisions differ under the microscope? Mayer and colleagues compared in vitro immunohistochemical and morphological aspects of penetrating corneal incisions. The femtosecond laser–created corneal incisions in human corneas showed no differences in inflammatory cell response but a significantly higher cell death rate than manually performed incisions, indicating an upregulated postoperative wound-healing response.

NO TOUCH SCLERAL SUTURED IOL
Posterior chamber IOLs have a theoretical optical advantage over anterior chamber IOLs due to their anatomic location and proximity to the nodal point of the eye. Anterior chamber IOLrelated corneal complications, such as endothelial compromise, pseudophakic bullous keratopathy, peripheral anterior synechiae, and subsequent glaucoma, may be minimized by positioning the IOL in the more “normal” anatomic location behind the iris. Researchers reviewed 78 cases treated with a modified no-touch transscleral sutured posterior chamber IOL implantation technique with a 1-piece monofocal IOL (Alcon CZ70BD) or an aniridia IOL (type 67G, Morcher). Indications included ocular trauma (46.2%), nontraumatic crystalline lens subluxation (16.7%), post-complicated cataract surgery (10.3%), idiopathic IOL dislocation (10.3%), and congenital cataract/aphakia (10.3%). An aniridia IOL was required in 39.7% of eyes. Overall, 91.3% of eyes had improved visual acuity or were within one line of the presenting CDVA. In the better prognosis group, 73.9% achieved a CDVA of better than 6/12 and all achieved better than 6/30, with a moderate rate of complications.
