Tamponade or Filling Effect: Changes of Forces in Myopic Eyes

Figure 1

Droplet of water at the end of a pipette. Molecule 𝛽, which is positioned inside the droplet, is equally attracted in all directions. Molecule 𝛼, which is located on the surface, is exposed to more attractive forces inside rather than outside the droplet, and the resultant attractive force is thus inwards. Surface tension acts like a film as it tries to achieve the smallest surface area for a given volume (modified from Kirchhof and Wong [74]).
