AIM: To compare the difference in corneal endothelial cell density and morphology after phacoemulsification using ringer lactate (RL) and balanced salt solution (BSS) irrigating solutions.
METHODS: The prospective randomized controlled trial study was conducted between February 2017 and April 2017 in Dr. YAP Eye Hospital, Yogyakarta, Indonesia. There were a total of 52 subjects (52 eyes) who were senile cataract patients further grouped into two, 26 patients undergoing the phacoemulsification procedure using RL irrigating solution and the other 26 patients with BSS irrigating solution, both conducted by one operator. On the 1, 7, and 28d post operative, an evaluation was done to measure the density and corneal endothelial cell morphology, as well as the variable of inflammation in the two groups.
RESULTS: Fifty-two eyes had undergone phacoemulsification with posterior intraocular lens implantation. Both groups were evaluated for the endothelial cell reduction and corneal endothelial cell morphology change, along with postoperative inflammation. On the 28d postoperative, endothelial cell reduction in the BSS group (173.96 cell/mm2, 8.12%) was lower than the RL group (253.20 cell/mm2, 10.25%), percentage of corneal endothelial cell variation coefficient increase in the BSS group (2.92%, 8.36%) was lower compared to the RL group (3.42%, 9.96%), decrease of hexagonal cells of corneal endothelium cells presentation percentage in the BSS group (4.30%, 8.17%) was lower compared to the RL group (4.84%, 8.97%), and the percentage increase of central corneal thickness in the BSS group (4.69 μm, 0.89%) was almost equal to the RL group (4.53 μm, 0.90%). All of the results regarding difference in density and corneal cell endothelium morphology between the two groups did not reveal any statistically significant difference (P>0.05). Inflammatory variable in the two groups were even.
CONCLUSION: BSS and RL were equal in their capability of maintaining endothelial cell loss and endothelial cell morphologic change in senile cataract patients after phacoemulsification.
Purpose: To compare the refraction outcomes after phacoemulsification in high myopia implanted withand without a capsular tension ring. Material and methods: This retrospective study reviewed all patientswith an axial length of 26 mm or more and had phacoemulsification with an intraocular lens (IOL) betweenJanuary to December 2019. Pre-surgery biometric measurement and IOL power calculation were performedby the Barret Universal II formula. The chosen IOL power to be implanted with the predictive refractiveoutcome (PRO) was recorded. One month post-surgery, auto-refractive objective refraction in SphericalEquivalent (SE) was measured and compared to the PRO. Results: Fifty four eyes from 38 patients hada mean age of 57.15 + 9.73 (SD). In the non-CTR group, significant statistical difference between the preto post-surgery outcomes of objective refraction was observed (p = 0.007), while in the CTR group therewas no significant statistical difference (p = 0.830). The CTR achieved an accuracy of 0.01 D + 0.32 (p= 0.010) against -0.36 D + 0.55 in the non-CTR group. The CTR group, also reached 88.5% PRO for farvision compared to 53.6% in non-CTR group (p=0.005). Conclusion: Phacoemulsification with CTR inhigh myopia resulted in better predictive outcomes.
