Outline

Text

Purpose: I have developed a new intraocular lens (IOL) that can be fixated in the eye with no capsular support, without using scleral sutures by simply setting the haptics in the ciliary sulcus. This new IOL has three haptics. Using porcine eyes, I introduce the technique to fixate the haptics of this IOL to the ciliary sulcus by using a new Haptics Manipulator that I have developed. I observe the stability of this IOL in the porcine eye by the new Miyake-Apple view using an otological rigid endoscope.

Methods: First, I use an endoscope and Ultrasound Biomicroscopy (UBM) to verify that the ciliary sulcus of the human eye has a sufficient groove to fixate the haptics. Next, using porcine eyes, I introduce the technique to fixate the three haptics of this IOL to the ciliary sulcus. To examine the stability of this IOL in the porcine eye, I push the optic of the IOL with a hook and forcibly push the section of the sclera where each haptic is fixed. In addition, I drop the porcine eye in which this new IOL is fixated from a height of 30 cm.

Result: The ciliary sulcus of the human eye has a sufficient groove to fixate the haptics. The incisions needed to insert this new IOL and to fixate its haptics to the ciliary sulcus are only one 4.1 mm corneal incision and two side ports. The new Haptics Manipulator was able to lead the haptics to the ciliary sulcus correctly and fix the IOL stably. The three haptics of this IOL were fixated correctly to the ciliary sulcus when I pushed the optic with a hook and pushed the sclera. The IOL was not dislocated or detached and its centering was good even when I dropped the porcine eye in which the new IOL is fixated from a height of 30 cm.

Conclusion: The IOL can be stably fixated intraocularly by fixating the three haptics in three points of the ciliary sulcus. The IOL also exhibits ample strength with respect to impacts from outside of the eye.

Only three corneal incisions are needed to fixate the new IOL intraocularly, with no sutures required. As a result, invasion of the eye was extremely slight.

Accordingly, this new IOL with three haptics is very useful and will bring a revolutionary advancement in the future to the ciliary sulcus fixation technique for eyes having no capsular support.
