Investigators in this prospective, non-comparative case series considered how patients fared in terms of quality of life after implantation of a new trifocal IOL, the PanOptix (Alcon, Fort Worth, Texas). Included in the study were 48 consecutive patients who had undergone bilateral implantation of this lens. A visual functioning index 14 (VF-14) quality of life (QOL) questionnaire was given 3 months after implantation of the second trifocal IOL. A subgroup of 14 patients with an interval of at least 3 months between the surgeries were also interviewed 3 months after monocular implantation. In this subgroup, QOL with monocular and binocular implantation was compared. The VF-14 questionnaire included a 0 to 4 point grading scale, with 0 indicating no difficulty and 4 signifying that the task was impossible to perform. Investigators determined that the most difficult tasks for those with the lens were driving at night, with a mean value of 0.89, reading small print, with a mean value of 0.94, and doing fine handwork, with of a mean of 0.64. Patient quality of life was improved with binocular implantation of the trifocal lens. Investigators concluded that with the PanOptix trifocal IOL patients have high vision-related quality of life, as well as a higher overall satisfaction rate as indicated by the mean values from the VF-14 questionnaire.

Posterior polar cataracts are among the most challenging and can require practitioners to use different strategies than they would with other types of opacities. In this study, investigators hone in on overcoming challenges associated with posterior polar cataract removal. To increase the likelihood of success, they discuss steps practitioners can take to enable fruitful preoperative counseling and strategic surgical planning including use of a thorough preoperative exam and appropriate diagnostics. With an eye toward keeping the posterior capsule protected as well as preserving options for IOL fixation, investigators describe specific techniques at each stage of posterior polar cataract removal.

New stains for anterior capsule surgery

The aim of this study was to determine if new dyes or novel combinations of these could offer lower toxicity than existing dyes, while offering equal or better staining in anterior capsule surgery. For the study, postmortem pig eyes with induced cataracts were stained and photography used to document results. Investigators determined that reduced toxicity on corneal endothelial cells could be attained with a new cyanine dye, known as BIP ((2-[5-[3,3-dimethyl-1-(4-sulfobutyl)-1,3-dihydro-indol-2-ylidene]-penta-1,3-dienyl]-3,3-dimethyl-1-(4-sulfobutyl)-3H-indolium sodium). By combining this green dye with trypan blue, staining here could be further enhanced. While methylene blue alone has a very toxic profile, this was reduced considerably when combined with trypan blue. Investigators concluded that the new green dye BIP allowed for safe capsule staining either alone or in combination with trypan blue.
