Mastel’s signature UltraThin Technology (100-120 _m). Neutral faceting bias. The vertical side is safety beveled so it will not cut in that direction, oblique sharp edges allow wound enlargement in one direction only. The tip truncation is very small so it penetrates the eye well while providing better free hand control when grooving. The first two edges connecting to this flat tip are of specific depths so the surgeon can gauge how deep the groove may be in either scleral or corneal tissue by skilled observation, using the shorter facet for shallower grooves or burying deeper and using the longer facet to provide slightly deeper grooves. Mounted in a straight dop configuration, the handle may be rotated to enlarge in either direction.
~Mastel maintains strict standards upon width and length, requiring diamond replacement at times to maintain performance standards.
~Straight dop only.
~Titanium President handle is a very robust design with more than ten thousand sold.

The Ahmed Super PentiAhm is a specialty design for cataract or other paracentesis requirements as well as free hand scleral groove applications related to glaucoma procedures. This facet design provides the surgeon with depth sighting references of 450 and 550 microns.
Designed in conjunction with Doctor Iqbal (Ike) K. Ahmed, this unique diamond fulfills a number of special purpose features for the cataract/glaucoma surgeon. Since the diamond has five actual cutting edges, it is important to point out that it is essentially a single edge blade to begin with, considering it has only one large cutting edge. This allows a beautiful paracentesis without the concern of inadvertent wound enlargement with patient movement (similar in nature to the metal 15 degree super sharps), yet wounds can readily be enlarged in either direction by rotating the handle 180 degrees, making it extremely versatile yet safe.
Next, the front three edges beginning with the truncated tip allow very clean groove incisions at the bottom of the wound, pierce nearly as well as a sharp tip yet slightly detuned, and allow much easier reentry into an existing incision when compared to a sharp tip blade. The two side angles that follow the tip on either side form what was the classic design in ophthalmology called the trifacet which was actually the first diamond blade geometry in ophthalmology dating back to the 1970s. These two edges are slightly different in length and allow surgeon visualization as depth indicators one being shallower and the other being deeper for freehand groove formation.
On the side that is not to be used for wound enlargement, we feature a sharp enhancement edge which makes a very clean wound margin entry since it trims the entry during a stab. Importantly, this side is turned down toward the globe when wanting to make a more controlled dissection vertically for deep flaps near Descemet’s membrane because the safety bevel acts as a sort of steady rest as it does not cut. So, a surgeon can tease a wound deeper as needed to find the structure planes in these difficult surgical maneuvers. All in all, this is one of the most useful and versatile diamonds we have ever developed.
