The Clinical Research Of Curing Pseudophakic Dysphotopsia By Glare Adaptation Treatment

Objective To investigate the clinical effects of treating PseudophakicDysphotopsia patients by glare adaptation treatment with flare light ofsynoptophore.Methods A total of 24 patients with age-related cataract (32 eyes) were selected.The patients had carried out phacoemulsification and intraocular lensimplantation in Huizhou Central People's Hospital form 2009.1 to 2009.10 anddeveloped obvious Dysphotopsia such as glare and halo within 1 week afteroperation. Inclusion criteria: (1) The patients diagnosed the age-relatedcataract preoperatively; (2)Operation procedure is phacoemulsification andintraocular lens implantation;(3)The class of glare symptom of patients isconsidered to be moderate or severe. the subjects were randomly divided into twogroups,blinded assessment is adopted. the treatment group(12 patients) acceptedglare adaptation treatment with flare light of synoptophore,compare to the controlgroup without treatment. The treatment group start the treatment at the secondweek postoperatively. The treatment last every 20 minute once a week, until threeweeks later. Vision Quality measurment included the comparison of the visualsymptoms (degree of glare and halos), the degree of impairment of the visionfunction and quality of life(VF/QOL), the total vision assessment ( satisfactionand trouble with vision), which assessed at 3 month and 18 month postoperatively.Results The scale of Vision function and quality of life (VF/QOL), visionsatisfaction, vision trouble,and the degree of halo have not statisticallysignificant between two groups 1 week, 3 month ,18 month after operation.The degreeof glare were different significantly between two groups 3 month after surgery.Before glare adaptability treatment, 100% patients with treatment group andcontrol group showed moderate to severe glare. Treatment group showed obviouslyreduced glare porportion after 3 month. While the proportion of control group also reduce,the difference have statistically significance(P=0.046).When comparethe 18 month to 1 week after operation betweening two groups, the difference haveno statistically significance(P=0.44). The proportion of patients with haloreduced with time expand in two groups. The difference have not statisticssignificance between two groups regardless of the short-term or the long-term.Conclusions glare adaptation treatment with flare light of synoptophore caneffectively reduce patients glare adapt time, improving glare symptom with earlystage patients. However,the effect of improving halos symptome have not bediscovered. Furthermore, according to 18 month long-term result, Treatment ofglare adaptation at earlier period had no significant clinical effect for thepatients with persistent and serious glare.
