The all-new <strong>Unity of 4<\/strong> &#8211; <strong>4D cataract surgery<\/strong> &#8211; now available at Sohana Hospital &#8211; brings a new level of control and precision. This advanced technology revolutionises how cataract surgery is performed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The term \u20184D cataract surgery\u2019 refers to the integration of real-time monitoring, pressure control, temperature regulation, and precision imaging technologies.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike traditional cataract surgery that relied heavily on manual techniques, 4D cataract surgery employs real-time monitoring for precision like never before. The \u20184D\u2019 label is not just a marketing gimmick &#8211; it\u2019s an indication of the technology\u2019s capacity to function across multiple aspects of surgical control.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Some features that make the technology stand out include &#8211; <strong>Intelligent Fluidics<\/strong>, <strong>Thermal Sentry Monitoring<\/strong>, and <strong>4-dimensional phacoemulsification<\/strong>. 4D cataract surgery\u2019s precision ensures there\u2019s minimal tissue damage during the procedure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Additionally, this advanced technology involves tiny incisions of just 1.6-2.2 mm. This is negligible compared to the 6-7 mm incisions made in old technologies (such as extracapsular cataract extraction). A smaller incision leads to minimal tissue trauma and faster visual recovery.<\/p>\n\n\n\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_79_2 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Read more on:<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/sohanaeyehospital.com\/blog\/unity-of-4-advanced-4d-cataract-surgery\/#4D_Cataract_Surgery_Features\" >4D Cataract Surgery Features<\/a><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/sohanaeyehospital.com\/blog\/unity-of-4-advanced-4d-cataract-surgery\/#Intraocular_Pressure_Control\" >Intraocular Pressure Control<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/sohanaeyehospital.com\/blog\/unity-of-4-advanced-4d-cataract-surgery\/#Thermal_Sentry_Monitoring\" >Thermal Sentry Monitoring<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/sohanaeyehospital.com\/blog\/unity-of-4-advanced-4d-cataract-surgery\/#4D_Phacoemulsification_Technology\" >4D Phacoemulsification Technology<\/a><\/li><\/ul><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/sohanaeyehospital.com\/blog\/unity-of-4-advanced-4d-cataract-surgery\/#Benefits_of_4D_Cataract_Surgery\" >Benefits of 4D Cataract Surgery<\/a><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-6\" href=\"https:\/\/sohanaeyehospital.com\/blog\/unity-of-4-advanced-4d-cataract-surgery\/#Quick_Procedure\" >Quick Procedure<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-7\" href=\"https:\/\/sohanaeyehospital.com\/blog\/unity-of-4-advanced-4d-cataract-surgery\/#Less_Energy_Use\" >Less Energy Use<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-8\" href=\"https:\/\/sohanaeyehospital.com\/blog\/unity-of-4-advanced-4d-cataract-surgery\/#Better_Lens_Placement\" >Better Lens Placement<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-9\" href=\"https:\/\/sohanaeyehospital.com\/blog\/unity-of-4-advanced-4d-cataract-surgery\/#Efficient_Cataract_Removal\" >Efficient Cataract Removal<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-10\" href=\"https:\/\/sohanaeyehospital.com\/blog\/unity-of-4-advanced-4d-cataract-surgery\/#Completely_Safe\" >Completely Safe<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-11\" href=\"https:\/\/sohanaeyehospital.com\/blog\/unity-of-4-advanced-4d-cataract-surgery\/#Bladeless_Painless_Stitchless\" >Bladeless, Painless, Stitchless<\/a><\/li><\/ul><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-12\" href=\"https:\/\/sohanaeyehospital.com\/blog\/unity-of-4-advanced-4d-cataract-surgery\/#Difference_Between_4D_Cataract_Surgery_Conventional_Cataract_Surgery\" >Difference Between 4D Cataract Surgery &amp;
