“…Therefore, we concluded that not the central corneal opacity size, but the size of corneal opacity covering pupil was the major prognostic factor for postoperative visual improvement. Patients with paracentral corneal opacity are the best candidates for cataract surgery to optimize vision [15]. But, if corneal opacity did not cover the whole central pupillary area, good vision can be achieved with cataract surgery and toric IOL implantation.…”

Background: To evaluate the effect of toric intraocular lens implantation in cataract patient with corneal opacity and high astigmatism.Methods: Thirty-one eyes of 31 patients who underwent cataract surgery with toric intraocular lens implantation were included. All patients had corneal opacity with astigmatism. Preoperative total corneal astigmatism was determined considering posterior astigmatism using a rotating Scheimpflug camera (Pentacam®: Oculus, Wetzlar, Germany). At 2 months after toric intraocular lens implantation, we evaluated residual astigmatism, uncorrected visual acuity (UCVA) and best corrected visual acuity (BCVA). Results: Postoperative UCVA and BCVA (0.30 ± 0.17, 0.22 ± 0.16LogMAR) were statistically improved compared to preoperative UCVA and BCVA (1.2 ± 0.34, 1.1 ± 0.30LogMAR, respectively) (P < 0.01). Postoperative residual refractive astigmatism (1.2 ± 0.35D) was statistically reduced compared to preoperative refractive astigmatism (2.4 ± 0.65D) (P < 0.05). Preoperative and postoperative total corneal astigmatism values were not statistically different. All eyes achieved postoperative visual acuity as good as or better than preoperative one. The size of corneal opacity covering pupil had significant negative correlation with postoperative UCVA and BCVA (logMAR) (R = 0.91 P < 0.05 and R = 0.92 P < 0.05, respectively). Conclusion: Toric intraocular lens implantation can improve UCVA, BCVA, and refractive astigmatism in cataract patient with corneal opacity. The size of corneal opacity covering pupil is the major prognostic factor for postoperative visual improvement. Therefore, toric intraocular lens implantation should be considered for cataract patients who have corneal opacity with high astigmatism.

“…Corneal edema was found in two eyes and reactivation of other corneal pathology in four eyes. Prafulla et al [16] reported that the use of 0.1% trypan blue with traditional coaxial illumination alone has been adopted as a safe and effective manner to improve visibility for cataract surgery associated with corneal opacities, although in some patients staining alone may not give accepted visualization. Sharma et al [4] reported that, the penetrating keratoplasty [PKP] combined with cataract surgery is a surgical choice for patients with corneal opacity with dense cataract.…”

Article informationBackground: Worldwide, cataract is the main cause of blindness. It accounts for 55%of 41 million blind. Visual restoring is made by cataract surgery. The aim of the work: This study designed to evaluate the use of endoillumination system in phacoemulsification in patients with hazy cornea and to assess its efficacy, complications, and the best way of using it. Patients and Methods: A prospective study included 40 eyes with cataract and hazy cornea were scheduled for cataract surgery, at Al-Azhar University Hospital [Damietta]. A comparison was made during each step of phacoemulsification with and without endoillumination. The post-operative assessment was performed on the first day, at the end of the first week, the first month, and the third month after phacoemulsification by best corrected visual acuity [BCVA], slit-lamp biomicroscopy and intraocular pressure measurement. Results: The mean age was 68.1 years; 28 patients were females and 26 had operation in the right eye. Capsulorhexis with illumination showed good results among 8 patients, 8 showed no change, and only two patients were worsened. However, without illumination, 16 patients had good results and 6 showed no improvement without any significant difference. In hydrodissection with illumination, 6 had good results and 4 showed no change. But, without illumination, 16 had good results, and 8 showed no improvement. The nucleus fragmentation with illumination revealed excellent results in 24 patients. However, without illumination, two patients had good results, 8 cases showed no improvement, and only two patients were worsened with a significant difference. Conclusion: Intracameral endoillumination improves the visual quality particularly the step of the nucleus fragmentation during cataract surgery.

“…In central corneal opacity, phacoemulsification should be performed when the extent of opacity is small enough to improve visual acuity after surgery. 15 In this study, we included patients with peripheral corneal opacity as demonstrated in Figure 7, and large central corneal opacity as in Figure 8. Patient with peripheral corneal opacity had more improved postoperative UCVA and BCVA compared to patient with central corneal opacity, in these cases.…”

Aims: To evaluate the effect of toric intraocular lens implantation in cataract patient with corneal opacity and high astigmatism. Methods: 31 eyes of 31 patients who underwent cataract surgery with toric intraocular lens implantation were included. All patients had corneal opacity with regular astigmatism. Preoperative total corneal astigmatism was determined considering posterior astigmatism using a rotating Scheimpflug camera (Pentacam: Oculus, Wetzlar, Germany). At 2 months after toric intraocular lens implantation, we evaluated residual astigmatism, uncorrected visual acuity (UCVA) and best corrected visual acuity (BCVA). Results: Postoperative UCVA and BCVA (0.30 ± 0.17, 0.22 ± 0.16LogMAR) statistically improved compared to preoperative UCVA and BCVA (1.2 ± 0.34, 1.1 ± 0.30LogMAR, respectively) (P<0.01). Postoperative residual refractive astigmatism (1.2 ± 0.35D) was statistically reduced compared to preoperative refractive astigmatism (2.4 ± 0.65D) (P<0.05). Preoperative and postoperative total corneal astigmatism values were not statistically different. All cases achieved visual acuity were as good as or better than that preoperatively. The percentage of corneal opacity covering pupillary area had significant negative correlation with postoperative UCVA and BCVA (logMAR) (R=-0.88 P<0.00001 and R=-0.87 P<0.00001, respectively) Conclusion: Toric intraocular lens implantation can improve UCVA, BCVA, and refractive astigmatism in cataract patient with corneal opacity. The percentage of central corneal opacity covering pupillary area is the major prognostic factor for postoperative visual improvement. Therefore, toric intraocular lens implantation should be considered for cataract patients who have corneal opacity with high astigmatism.
