Abstract:·AIM:To study the effect of operation and laser and application of IOLmaster and OLM(opacity lensmeter)on patients with cataract and shallow anterior chamber.·METHODS:Totally 106 patients 128 eyes with cataract and shallow anterior chamber were divided into mild and severe groups by anterior chamber depth,mild,moderate and severe groups by lens density.Some patients received phacoemulsification or laser treatment.They were observed and analyzed for 2 years.·RESULTS:No operation group:The conditions of anterior chamber and intraocular pressure(IOP)are more serious than before in mild and severe anterior chamber groups during 2 years(P<0.05);With the worsening of lens density,the conditions of anterior chamber and IOP in severe lens density group were more serious than that in other two groups during 2 years(P<0.05).Operation group:After 2 years the high IOP rate of patients with operation was lower than that without surgery treatment(P<0.05);The conditions of anterior chamber and IOP of patients with operation was better than before and that without surgery treatment(P<0.05);The best-corrected visual acuity(BCVA)of all patients is improved after surgery than before(P<0.05),while the BCVA of patients in severe anterior chamber group after operation was lower than that in mild anterior chamber(P<0.05).Laser treatment group:1 years later,IOP of patients with laser treatment in mild anterior chamber group was not significantly improved than before(P>0.05),while IOP of patients with laser treatment in severe anterior chamber group was more worse than before(P<0.05)though laser treated successfully.·CONCLUSION:IOLmaster and OLM can offer the assessing of progression of the patients with cataract and shallow anterior chamber.Earlier surgery of cataract is more effective than laser treatment though with a little difficuty.·
