\"Which<\/p>\n

When considering a corner opening to widen the area of the eye, many people worry that the result will look unnatural. How the proportion between the lower and the outer opening is set is what governs that. The two pull in different directions and work on different structures, so opening too far in one direction alone can throw the eye’s width-to-height proportion out of true.<\/p>\n

Many patients combine the two in the hope of a large, open eye. But widening the scope without regard to the skeletal limits of that particular eye can disturb the harmony of the result or bring functional discomfort.<\/p>\n

A lower-corner opening brings the lower lid down and adjusts the vertical dimension; an outer-corner opening moves the lateral canthus outward, horizontally, and lengthens the eye. The two act along clearly different vectors, so carrying out either alone without looking at the present proportion leaves room for the balance of width and height to be lost.<\/p>\n

What follows covers the anatomical limits to consider in a combined opening, and why the proportion matters.<\/p>\n

Which eyes need a lower-corner opening?<\/h2>\n

A lower-corner opening brings the outer part of the lower lid down and adjusts the angle of the corner. Unlike an outer-corner opening, which widens the eye from side to side, it works on the vertical and on the angle, so the impression each one changes is different.<\/p>\n

It can be considered where the following apply.<\/p>\n
