After Different Type Artificial Lens Implantation Anterior Chamber Change And Significance

Objective:By phacoemulsification equipment and ceaseless operation technology improvement with small cut and gradually mature, foldaway artificial crystalline lens ceaselessness ameliorates and, cure cataract now when combining to shut the angle type glaucoma patient, that simple part patient line cataract surpasses sound emulsifying reaching the rear-room of a house type manpower crystalline lens implantation being OK uses notable lessening of intraocular pressure, gains the comparatively good curative effect. But intraocular pressure lessening effect is more obvious, the anterior chamber opening to the outside world degree is especially ideal after which once grows foldaway artificial crystalline lens to the skill be that we need investigation and discussion's one problem. Different foldaway artificial crystalline lens volume different to some extent, different function foldaway artificial crystalline lens props up degree to irides different to some extent, degree and the anterior chamber open degree piece therefore skill queen intraocular pressure comes down may different to some extent. through uses ultrasound biomicroscoPy (UBM) to cataract surgery around the anterior chamber quantification survey and the comparison as well as to cataract surgery around the intraocular pressure change situation observation, after the discussion different type artificial lens implantation, the anterior chamber shape and the intraocular pressure change rule as well as to the possibility has the glaucoma outbreak sickness group choice artificial lens to do refers.Methods:Chooses 60 examples (87 eyes) cataract patient. Divides into 3 groups stochastically, A group is three piece of types (Senser) the group, B group is a piece of type (Natural) the group, C group is a piece of type (Rayner) the group, but the artificial lens itself volume is big. The line of supersonic emulsified cataract ablution union foldaway artificial crystalline lens implantation, uses the artificial lens separately before the Surgery and the Surgery latter 3 months surveys the anterior chamber depth and the anterior chamber angular width change with the ultrasound biomicroscoPy (UBM) quantification, the observation artificial lens position and after the technique in 3 months surveys the intraocular pressure.Results:1st,In all Patiens there was significant difference(P<0.05) of ACD(anterior,chamber distanee), TIA500 (trabecular-iris angle at 500um from the scleral spur),AOD500 (angle-opening distanse at 500 um from the scleral spur) and AOD250 (angle-opening distanse at 250 um from the scleral spur).2nd, after the Surgery for three 3 months group of central chamber depth (ACD):A group change is bigger than B and C group (P<0.05). the change of trabecular-iris angle at 500um from the scleral spur of A group and B group is bigger than C group obviously (P<0.05), A group with B group has not obvious difference. The 500um and the 250um place anterior chamber openings is away from three not obvious differences. 3rd, after the Surgery, the intraocular pressure has the certain extent compared to before the Surgery to drop, the former and the latter comparison has the significance difference (P<0.05). before after the supersonic emulsified cataract ablution union artificial crystalline lens implantation's anterior chamber compares to before the Surgery, anterior chamber obvious deepening, anterior chamber obvious broaden, intraocular pressure obvious drop.2nd, three piece of types (PMMA climbs arches 5°included angle) the artificial lens to be big to the central anteroom depth influence, own volume is small, the iris included angle influence are super to others at 500um from the scleral spur.
