The lens diameter is 4 mm and the lens has no haptics in the conventional sense but is finely grooved around the circumference edge. The lens is inserted into the anterior capsule via a very small-diameter opening created by mini-circular capsulorhexis. The anterior capsular opening, with a round, smooth-edged margin, avoids stress concentration and, therefore, the capsule does not easily tear. This opening catches the lens and chokes it along the grooved edge. In animal experiments, firm fixation was obtained. This lens may be adequate for small-incision surgery, and in the future it may be used to prevent leakage of filling material during refilling of the lens, since it acts as a part of the anterior capsule and seals the capsular opening completely.
