The study looked at a new eye surgery method that leaves a tiny piece of membrane over the center of the retina, instead of removing it completely. It found that keeping this membrane reduced the chance of developing a macular hole and helped maintain vision better over several years. This research is about eye surgery, not about the peptide selank, so it doesn’t provide useful information for biohackers or health‑optimizing enthusiasts.

To investigate the long-term results of a novel technique to preserve the foveolar cone without peeling off the foveolar internal limiting membrane (ILM) during myopic traction maculopathy surgery. Nineteen patients (19 eyes) were retrospectively studied and divided into 2 groups by the extent of ILM peeled and followed for more than 3 years. Group 1: foveolar ILM nonpeeling group (FN) (12 eyes) and Group 2: total peeling of foveal ILM group (TP) (7 eyes). A donut-shaped ILM was peeled off, leaving a 400-μm diameter ILM over foveola with a sharp margin in FN group. Macular hole was developed in 2 of the 7 eyes (28.6%) in the TP group and none in the FN group. Long-term central fovea thickness thinning and decrease of vision were found in the TP group, but not in the FN group (P < 0.05). Inner segment/outer segment line recovered in 75% of the 12 eyes in the FN group, but in only 14.3% of the 7 eyes in the TP group. Preservation of the foveolar cone by foveola nonpeeling surgery correlates with better anatomical and visual results than total peel, prevents long-term foveolar retinal thinning, and successfully saves the fovea from macular hole formation.
