“…Similarly, Abd-Elhafez in 2019 also reported a significant increase in macular thickness when compared preoperatively and one week postoperatively. Although, no difference was seen in macular thickness at three months postoperatively [14]. In the current study, no significant rise in CMT was observed two weeks postoperatively when compared to the preoperative values of CMT.…”

IntroductionOpacification of the posterior capsule is labeled as a secondary cataract. The objective of the current study was to assess central macular thickness (CMT) changes following neodymium-doped yttrium aluminum garnet (ND-YAG) posterior capsulotomy and to find out the correlation between CMT with the age, energy, and total shots utilized during the procedure. MethodologyIn this single-centered prospective observational study, 137 patients with a mean age of 57 ± 12.61 years, who had cataract surgery previously and were candidates for ND-YAG posterior capsulotomy were recruited through consecutive sampling. The study was conducted at Layton Rahmatulla Benevolent Trust (LRBT) Free Eye Hospital, Township, Lahore, Pakistan, between April 2020 to April 2021. The CMT, total energy, and sum total of shots used were recorded. The thickness of the central macula was measured preoperatively and postoperatively after two weeks. The paired sample t-test was used to find out any significant changes in CMT pre and two weeks postoperatively. The comparison of changes in CMT to age, energy, and the total number of shots was made through Pearson correlation. Means of CMT were compared using an independent sample t-test, at two weeks postoperatively among two energy groups. ResultsNo statistically significant differences were found between preoperative and two weeks postoperative values of the CMT (P-value= 0.209). No significant difference was found in CMT statistically among the two energy groups (p=0.11). The patient's age, sum total of laser shots, and aggregate of laser energy did not have any significant correlation with CMT changes. The time period between cataract surgery and ND-YAG surgery showed a moderately positive correlation with a p-value of 0.01. ConclusionThe current study revealed that ND-YAG capsulotomy does not affect the CMT significantly postoperatively. The patient's age, total energy applied, and the total number of laser shots used do not influence the macular thickness. However, the length of duration from the last cataract surgery to the current surgery was significantly associated with a change in the CMT.

“…other studies done by (5) whose study was on 100 eyes of 100 patients, (6) whose study was on 160 eyes, 95% of the patients had visual function improvement, In the study done by (7) , The mean macular thicknesses was decreased postoperatively at four weeks with mean (247.27 ± 12.54 µm) which was not statistically significant and decreased at three months with mean (243.27 ± 12.69) which was highly statistically significant.…”

Background: Posterior capsular opacification (PCO), also called 'secondary' or 'after' cataract, develops a few months to a few years over the clear posterior capsule after an uncomplicated cataract surgery that causes decreased vision. Purpose: To evaluate the impact of Neodymiumdoped Yttrium Aluminum-Garnet (Nd: YAG) laser capsulotomy on the central macular thickness (CMT) by optical coherence tomography (OCT) in patients with opacified posterior capsule. Patients and Methods:This is a prospective clinical study conducted on 30 pseudophakic patients recruited from Luxor International Hospital and Beni-Suef University Hospital during the period from December 2018 through August 2019. Their age ranged from 40 -70 years with a mean ± SD of 56.0 ± 8.89 years. There were 19 females (63.3%) and 11 males (36.7%). Results: There was highly statistically significant increase in CMT 1 week post YAGYAG laser than pre-YAGYAG with a mean thickness of 253.80 ± 14.03 µ vs 241.53 ± 10.22 µ respectively with a P-value < 0.001. Four weeks post YAGYAG,, CMT decreased to 247.27 ± 12.54 µ (P= 0.186) which is non significant. At 12 weeks post YAGYAG CMT decreased to 243.27 ± 12.69 .with p-value < 0.001 which is highly statistically significant. Conclusion: Increased CMT was reported as complication of YAG laser posterior capsulotomy. Although this is not clinically observed but follow up with OCT revealed these changes. However, this might not necessitate regular prophylactic treatment.
