PROPOSE: To compare the decentration and tilt between Aquasense(R) and Acrysof(R). METHODS: The subjects of this study were 48 patients (56 eyes) with Aquasense(R) and 44 patients (49 eyes) with Acrysof(R). Each posterior chamber intraocular lens (PCL) was inserted into the capsular bag after continuous curvilinear capsulorhexis and phacoemulsification. The decentration and tilt of Aquasense(R) and Acrysof(R) were measured 1 day, 30 days and 60 days postoperatively using anterior eye segment analysis system (EAS-1000, Nidek, Japan). RESULTS: The decentration showed no difference between Aquasense(R) and Acrysof(R) on 1st (P=0.19), 30th (P=0.07) and 60th (P=0.06) postoperative day. The tilt showed no difference between Aquasense(R) and Acrysof(R) on 1st (P=0.4), 30th (P=0.47) and 60th (P=0.22) postoperative day. CONCLUSIONS: The decentration and tilt of the two intraocular lenses showed no difference on the 60th postoperative day.

PURPOSE: In a preliminary series of 36 eyes with partial nasolacrimal duct obstruction, the types of dacryoscintigraphy result were classified and the results of silicone tube intubation were analysed. METHODS: The results of dacryoscintigraphy, performed in 36 eyes of 29 patients with partial nasolacrimal duct obstruction, were classified into the following 3 types: pre-lacrimal sac type, proximal nasolacrimal duct type and distal nasolacrimal duct type. Punctoplasty accompanied by silicone tube intubation was conducted selectively. RESULTS: In dacryoscintigraphy, symptoms improved in 6 eyes among 6 in distal nasolacrimal duct type (100%), 14 eyes among 18 in proximal nasolacrimal duct type (77.8%) and 8 eyes among 12 in pre-lacrimal sac type (66.7%). CONCLUSIONS: We conclude that dacryoscintigraphy predicts the results of silicone tube intubation. Furthermore, silicone tube intubation was effective in proximal nasolacrimal duct type and distal nasolacrimal duct type, but less effective in pre-lacrimal sac type of partial nasolacrimal duct obstruction.
