The impact of corneal guttata on the results of cataract surgery

Visual and satisfaction results with implantation of the trifocal Panoptix® intraocular lens in cataract surgery

“…In addition, the results of the validated Spanish CATQUEST-9SF satisfaction survey that was applied to the patients 20 , 21 . The ordinal raw data from the CATQUEST-9SF questionnaire were converted into a Rasch person score, with an interval level measurement called logit unit 21 , 22 . A logit is the natural log-odds of a respondent's successful completion of an item against failed completion.…”

“…A logit is the natural log-odds of a respondent's successful completion of an item against failed completion. A negative logit score indicates that the level of capability is above average of the necessary degree of demand for the items 21 , 22 .…”

Effect of Reformation of the Anterior Chamber by Air or by Ringer’s lactate solution on Corneal Endothelial count and morphology after Phacoemulsification

“…Corneal endothelial permeability does, however, gradually increase as central endothelial cell density decreases below 2000 cells/mm2, but compensatory metabolic pump mechanisms keep the cornea at its normal dehydrated state until a central endothelial cell density of 500 cells /mm2 is reached 9 . A number of factors are known to acutely affect the barrier function of the endothelium including reversible disruption of cell junctions during irrigation with calcium free solution or glutathione -restricted solutions, mechanical damage during intraocular surgery, or chemical injury due to introducing non-physiologic or toxic solutions into the anterior chamber 10 . The human corneal endothelium cannot undergo any form of regenerative healing to replace dead or injured endothelial cells.…”
