For the port-fixation group, supranasal and inferotemporal trocars (25-gauge) were placed in the center of a T-shaped lamellar scleral incision 2 mm from the corneal limbus and a supratemporal trocar at 3.5 mm. Following a vitrectomy, along with lens or IOL extraction as needed, the infusion cannula was changed from an inferotemporal to supratemporal trocar. The first IOL haptic and trocar were then simultaneously withdrawn from the eye by grasping with vitreoretinal forceps, with the same performed for the second IOL haptic and trocar, after which the infusion cannula was removed. In the conventional group, 2 T-shaped scleral incisions and three trocars were separately placed.Results: Postoperatively, transient ocular hypotension and hypertension were observed in a few eyes in both groups. At 6 months after surgery, astigmatism was 1.71± 1.13 D in the port-fixation group and 2.21± 1.78 D in the conventional group (p=0.40, t-test).Conclusion: This new technique may be effective because of the lower number of scleral wounds.Keywords: intraocular lens, intrascleral fixation, cataract surgery, lens subluxation, vitrectomySuzuki YTando TAdachi KKudo TNakazawa MDove Medical Pressarticleintraocular lensintrascleral fixationcataract surgerylens subluxationvitrectomyOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 14, Pp 1223-1228 (2020)
