Abstract Details
Purpose:
The aim of the study was to examine the procedure and influence of neodymium:yttrium-aluminum-garnet ( Nd: YAG ) Laser Capsulotomy on the condition of WIOL-CF intraocular lens.
Setting:
Departament of Ophthalmology, Prof. Gibinski University Clinical Center of the Medical University of Silesia, Katowice, Poland.
Methods:
The analyzed group consisted of 20 presbyopic patients (13 man and 8 women, age 23 to 77y) implanted with polyfocal full-optics intraocular lens (WIOL-CF, Medicem, Cz). Four eyes of 3 patients scheduled to undergo Nd:YAG laser capsulotomy were recruited between 6-12 months after cataract operations. All capsulotomies resulted in a central opening of the posterior capsule. Pre- and post-intervention values of refractive and visual parameters were compared. There were assessed: position and centration of the IOL, Nd:YAG parameters, visual acuity, contrast sensitivity, AS – OCT, WASCA , defocus curve in patients after IOL implantation.
Results:
Before Nd:YAG laser capsulotomy, correlation existed between the PCO value and visual acuity Contrast sensitivity (CS) were also weakly correlated with the PCO value, but the correlation coefficients were smaller than that of visual acuity. After Nd:YAG laser capsulotomy, UDVA averaged 0,2 logMar to 0,0 logMar ,UCIVA improved from J5 to J3 and UNVA from J3 to J2. Contrast sensitivity was increased in all spatial frequencies (3.0; 6.0 ;12.0 ;18.0 cpd) , without statistically significant difference . All visual angles improved. Laser parameters changed depending on the posterior capsule thickness. No IOL decentration was observed.
Conclusions:
The Nd:Yag photodisruptive laser offers a swift, safe method for dealing with the posterior capsule opacification. After capsulotomy, the visual functions improved and the results were stable in the follow-up time
